…So…you remember how my grandpa (who I called and still call Papa) passed away? Well, my grandma/Nani has gone to join him and the Lord Jesus in heaven...it's been a hard year. It's been a hard since 2015 and still pushing onward to 2016 and probably further on. I'm sorry that I'm being such a downer, but…I just need some comfort right now.

No, I'm not asking you guys to feel sorry for me or have me expect you to treat me any different; it's life. I believe that she's in heaven with my/our Lord and Savior Jesus Christ, and is with her family and husband celebrating and praising Him forevermore. She's not suffering any longer and I'm happy for that. I just didn't think she'd go this soon.

Even my parents thought that she'd stay for a while longer; we thought that this would be a year for mourning. God just had other plans…and it really showed. Nani just faded after Papa's funeral; she was losing weight, getting sickly to the point of being hospitalized in April, etc. The point is, Papa was her rock, and it obviously affected her along with other things such as her older sister dying soon after.

My Nani touched many people, and so many people came to mourn for her; I knew how amazing of a grandmother she was, but I never stopped to wonder how great of a person she was until after she was finally gone. I'm so glad for her life, and I'm blessed that I had a grandparent like her. I only wish…that they blessed and made her a frigging Saint, because DANG IT she deserved it (she's Catholic, btw; I, however, am a Protestant Christian).

So, it's been pretty hard, and her sickness was one of the reasons why I haven't been writing much. I've been using the computer as a means for school and comfort/distraction; I don't really like thinking about death on account of how it affected me last time this happened, but it's something that we all have to deal with and so I just have to accept it. Thank you all for your support and I'm sorry for the delay.

Now…let's continue this, shall we?

Chapter 4: The Ruins

(~)

"Aaaaand…done!"

Phineas rose up his screwdriver and took a look at his phone. No longer a walkie-talkie sort of device, it had been completely transformed into a flip-phone with an orange and blue cover with silver linings. The antenna had been replaced by a stub where it once was. Phineas smiled.

"Alright, let's see if it works," Phineas said, dialing on his cell, "Hm…wait," he paused, "How would a phone work underground? Is there even wi-fi down here?"

Phineas looked up at the ancient ceiling and stood to his feet, wandering as he continued to stare up. Maybe there were some wires, or something. Phineas didn't exactly know how it worked in the Underground, or even how it would work, but he would find out, darn it. He wasn't really paying attention, however, and was surprised when his phone started to ring.

Phineas looked down to his phone, opened it, and put it to his awkwardly place ear. "Hello?" he asked.

Toriel voiced through, "Hello? This is Toriel. You have not left the room, have you?"

Phineas paused, lifted his head up once again, and took a survey of his surroundings. How did he wander out here, he wondered as he realized he was no longer standing beside the pillar and had entered another spacing. He didn't get a chance to answer Toriel's question, as she went on:

"There are a few puzzles ahead that I have yet to explain. It would be dangerous to try to solve them yourself. Be good, alright?"

Phineas was silent for a few seconds before answering, "Okay. I will."

"I will be back very soon, my child! Just need to get a few things…"

The phone clicked off. Phineas placed the device into his pocket, his smile, though well-meaning to the common eye, would be turning slightly devious to someone who could read his thoughts. "Well…I'm already out here," he said, "It wouldn't hurt to look around for a tiny bit."

Not being able to fight off his curious-driven temptation any further, Phineas decided that he should, no, that he must explore the place further! Who knows? Perhaps he would find his friends that way. Phineas, pleased with his reasoning with himself, stepped forward.

"Ribbit, ribbit."

Phineas paused at the familiar sound croaking beside him. He turned slowly to none other than a Froggit. Phineas stared at it, and their gazes seemed to intensify. Phineas blinked, and underneath the fake body, so did the Froggit. "…Uh…" Phineas rose up a hand and waved, "Hello?"

"Ribbit, ribbit."

Phineas blinked again, wondering if this was the same Froggit that attacked him from before. Somehow he doubted it, given that Toriel had gone through there already. Phineas assumed that the Froggit who had tackled into him was hiding somewhere.

"Ribbit, ribbit (Excuse me, human)."

Phineas gave a slow, awkward smile. What was he supposed to say? "I like the way you sound," he managed to say, "It's…very frog-like."

The Froggit did not seem to care about what Phineas said and continued croaking. Phineas chuckled more nervously.

"(I have some advice to give to you about battling monsters,)" the Froggit said, "(If you act a certain way or fight them until you've almost defeated them…)" it craned its fake body towards Phineas, "(They might not want to battle you anymore. If a monster does not want to fight, please…)" it bowed its 'head', "(Use some mercy, human.) RIBBIT."

Phineas tilted his head at the creature who continued to stare at him. "…I have no idea what it's saying," he admitted to himself before looking towards, what a surprise, another room that stood beside the Froggit. Phineas smiled. "Ooh, what's in there?" he asked as he walked around the Froggit into the room.

The Froggit watched as the human entered, and he sighed as he knew very well that the human understood him as little as he understood the human. "Ribbit…(Curse my inability of speech…such irony…such is fate…)"

Phineas looked around possibly the smallest room in the entire building thus far. He looked over to the water on his left and on his right, as well as at the plant life. He would've immediately been bored by this display had it not been for the small pillar holding a bowl of candy. He grinned, ignoring the square of dead leaves pinned around it. He peered into the bowl, and saw a small, tiny piece of paper that said "take one".

Phineas stared and let out a calming breath. "I cannot disobey the words of paper," he said, as if above transgression itself, and quoted Ferb, "Thine is law."

In spite his noble words however, Phineas snuck one, and then another piece of candy. He looked around to make sure no one saw him practically break the law.

How disgusting…

Phineas rose his head up at the sound in shock, looking around again. No one. Not a single person or thing was there. He glared up to where he thought the sound was coming from. "Fine, fine," he groaned, "I'll put it back…"

Phineas reached out to the bowl, in an attempt to place the candy back. As if it were a magnet, however, another piece latched itself to his hand. Phineas stared at the three pieces of candy in his hand.

You feel like the scum of the earth…

Phineas gasped, looking back up to the sound, wherever it was, and felt his chest tightened. He no longer craved the sugary sweets and attempted to force them all back down into the bowl, but the force caused him to tip the bowl of candy over, soiling it all. Phineas stared in horror, at the pile of sweetness gone to waste, and the four pieces of candy in his hands.

Look at what you've done.

Full of guilt and terror, Phineas ran out of the room, his eyes widened as he shrieked. He put the pieces of candy in his pocket, deciding that he would not let their fallen brethren die in vain. Once Phineas had calmed himself, he looked back to the room, dumbfounded. "Okay…so…that happened," Phineas looked down the path, seeing more dead leaves on the ground.

As Phineas went, he stepped on the leaves, remembering the autumn time when he, Ferb, and his friends would jump into a giant hill of leaves that he and his brother had made themselves for them to play in. Candace would assume that to be foul play, of course, but no one else seemed to mind, even if the pile of leaves had been the height of mountains, even taller than Mt. Ebott. Candace thought everything was foul-play, didn't she? Ever since their parents…left…she had been nosier than ever. Nosey enough for even someone as oblivious as Phineas to take notice.

Phineas rolled his eyes as he began to playfully crinkle through the leaves as he went along, forgetting about his recent sins against the heavens. It filled him with determination.

Suddenly, he tripped over, falling onto the ground face first. Phineas pushed himself up, rubbing his nose before looking behind him to see a small, sobbing figure. Phineas gasped at the monster, a creature with the appearance of an insect with two drooping antennae, two small wings, and two little arms and legs. Its body shape resembled that of a ghost. Its current expression was tear-filled sadness, with an open frowning mouth and eyebrows. It was crying, or rather whimpering, as softly at it could.

Phineas reached out to the creature. "I-I'm so sorry!" he said, "Are you o-?"

Halfway through Phineas' words, the creature burst into tears and flew away. Phineas watched as it fled, and ran after it immediately, unaware that it was leading him further away from where he was supposed to be. "WAIT!" he called out, "I don't want to hurt you! I just wanna talk!"

Phineas chased after the sobbing monster, but not for long. For as soon as Phineas reached a certain point in the path, the floor below him crumbled, sending him falling. He landed on an even bigger pile of red colored leaves. Unlike the flowers that had broken his fall before, however, the leaves did less, and even though they cushioned the fall, he still felt sore. Luckily, no real damage could be caused by such a short fall. He rubbed his buttocks, groaning.

"Ugh…what's with me falling today?" Phineas asked himself. He looked up. "Was that a trap? I think that was a trap!"

Well, no shit, Sherlock, what was your first clue?

As the boy looked around, he quickly found two flights of stairs, one of one side of the pile of leaves he currently resided on, and one on the other. Phineas took the other flight of stairs, and quickly got out of his predicament. However, the sad creature he was chasing after was nowhere to be seen. He glared at the "trap". Now that he thought about it, it served more as a nuisance than an actual trap, especially given the stairs that led outside of it.

Worry filled Phineas for the poor creature, and he went forward. The next room consisted of a rock lined up in front of some kind of panel, while further down was a barricade of spikes coming out of the floor. Phineas didn't have the chance to further survey the room when his phone rang again and he answered.

"Hello? This is Toriel," his friend said, "For no reason in particular…Which do you prefer? Cinnamon or Butterscotch?"

Phineas almost went with butterscotch, but it reminded him of the bowl of candy that he knocked over (honestly, who on this earth would feel this guilty about something like that?), and went with cinnamon instead. The speed of his answer made Phineas believe for a moment that Toriel would've thought something was wrong, but instead she spoke evenly, "Oh, I see. Thank you very much!"

And with that, Toriel hung up. Phineas smiled as he continued to look around before the phone rang again as soon as he took another step.

"Hello, this is Toriel," the lady monster said, "You do not DISLIKE butterscotch, do you? I know what your preference is…would you turn up your nose if you found it on your plate?"

"Well…I'm fine with either one," Phineas admitted with a patient smile.

"Right, right," Toriel said, and Phineas could hear her nod through the phone, "Thank you for being patient, by the way."

The phone hung up, and Phineas sweated a little. Should he really keep going now? "Well…I should find that flying monster and see if it's okay," he reasoned, "Besides…" he smiled at the puzzle, "I'd like to give this a try."

In spite knowing that the obvious route would be to push the rock forward, Phineas' instincts went to yet another sign on the wall next to him. He frowned at the text, not sure what he was initially expecting.

Three out of four grey rocks recommend you to push them.

Without a clue as to what the sign meant, Phineas shrugged and went to the grey raggedy stone that was about a sliver shorter than him. Despite the size, the rock was surprisingly easy to push onto the panel, which caused the spikes to lower themselves into the ground. Phineas smiled as he walked passed the floor and down the next hall.

"Man, this place is huge," Phineas commented, "It's kinda nice, though, for a Ruins. Though…I would've thought Ruins would look more…uh…ruinous…"

He paused and felt his jaw drop as before him was a long pathway of unstable ground, covered in cracks not too different from the ones that sent him careening downward while he chased after the flying monster. Phineas stared and he examined the floor before him. Squinting, he carefully took a step forward and to his surprise saw that it was sturdy enough to support his weight. He smiled and took another step, only to find himself once again falling through the floor and landing on yet another pile of leaves, place intricately for reasons Phineas didn't understand. He groaned.

"Time to do this the lazy man's way…"

Phineas took out his phone once again and dialed a seemingly random number. For whatever reason, a large propeller slipped out, and proceeded to lift Phineas up from the ground, out of the trap and over the rest of the dangerous looking pathway. He reached the other side and continued forward, shutting off the propellers as he did.

In the next room was a set of three rocks, much like the first movable one in the other room. In front of the rocks was an even thicker set of spikes coming out of the floor than the last. Phineas looked immediately proceeded to push the rocks. "Hm…you know," Phineas thought to himself as he finished pushing the second of the three rocks, "I just realized something…if Miss Toriel went through this path, then she must've gone through these puzzles. How in the world did they reset on their own?"

Before he could come up with a logical answer, suddenly, the third rock of which he proceeded to push suddenly spoke. "WHOA there, pardner," it spoke, "Who said you could push me around?"

"Oh, I'm sorry," Phineas apologized, "I didn't realize you were…"

Phineas didn't know why, but in spite the fact that rocks indeed have no faces the rock appeared to be eyeing him up and down in a way that made it seem displeased. "Didn't know that I was what?" it asked with…gritted teeth? This place was getting weirder by the minute.

"N-nothing," Phineas quickly said, clearly his throat, "Nothing at all, nothing…at all…uh…do you think you can move, please? I need to get through the puzzle."

The rock hummed in blaring thought. "So you're ASKIN' me to move over?" it asked to verify, though it didn't wait for Phineas to answer, "Okay, just for you, pumpkin."

The rock inched only a little forward towards the dial, and stopped immediately. Phineas blinked, looking back and forth from rock and to the panel before poking at the rock again. "Excuse me," he said politely, "But I'm gonna need you to move a little more, please."

The rock hummed louder than the last time, and Phineas assumed that it must've had hard of hearing. He couldn't blame it, since it appeared to have no ears at all. "You want me to move some more?" it asked, "Alrighty, how's this?"

The rock moved once again, but off of the alignment of the panel, and onto the side. Phineas stared at the rock, shook his head, and said, "Uh…no, no, I need you to get on the panel, please. You're going the wrong way."

The rock hummed, louder than the last two times. "That was the wrong direction?" it asked, "Okay, I think I got it."

With that, the rock proceeded to move back to the alignment and slid all the way onto the panel, allowing the spikes to hide into the ground and allow passage. Phineas grinned, nodded at the rock, and proceeded forward. Before he could continue on his merry way, however, the spikes shot up suddenly, nearly piercing Phineas' foot had he not stumbled back. He looked over to the rock once again and saw that it had moved off of the panel. Phineas went back over to the rock, which seemed to sigh as if to ask what the boy wanted from it now.

"You need to stay there a little bit longer, sir…ma'am…yoooouuu…" Phineas explained awkwardly.

The rock let out the loudest thoughtful hum that Phineas had ever heard. It seemed to put all of its strength into the hum. Why such a thing filled him with determination was beyond even him. "You wanted me to STAY there," it concluded with another sigh, "You're giving me a real workout."

The rock once again slid back onto the panel, and the spikes once again retreated into their respective holes. Phineas thanked the rock before continuing on his way to the next room. To Phineas' surprise, it was not another puzzle, but instead consisted of a single table that had cheese on it. He went over and tried to pull the cheese off, but realized that it had been there for so long that it was now stuck onto the table. Phineas looked over to see a mouse hole on the wall, and realized that a mouse must be trying desperately to get the cheese.

Knowing the mouse may one day leave his hole and get the cheese…it filled Phineas with determination.

And so, Phineas continued forward with his spirits rising as optimistically as it did usually. So far, these puzzles were a breeze, and the encounters he had made with other monsters…now that he thought about it, wasn't he forgetting something? Ah well. He'd remember later.

Phineas paused as he looked at the newest form before him and stared blankly. What it looked like was a child with a sheet over his head, with holes to see through. Of course, this looked more realistic as far as cartoonish looking ghosts were, lying down, staring up at the ceiling lifelessly.

Well, not lifelessly. He seemed to be breathing. In fact, he seemed to be sleeping. With his eyes opened.

"…Hello!" Phineas greeted, waving, "I'm very sorry. But do you think you can…move out of the way?"

"ZZZZZZZZZZZZZZZ…" the ghost-like pillow sheet said/snored, "ZZZZZZZZZZZZZZ…ZZZZZZZZZZ…(are they gone yet?)… ZZZZZZZZZZZZZZZ…"

Phineas stared as the ghost continued to say "z" loudly, pretending to sleep. The child blinked and looked around, shuffling a bit as he waited for an actual answer. After waiting a bit, he tried again. "Hello? Mr. Ghost-Pillow-Sheet-Person?" he asked with a louder tone, "May you please move?"

"…ZZZZZZZZZZZZZZZ…"

"…Wait…if he's a ghost…then I can just walk right through him!"

With that mindset, he decided to move forward and continue on his-

Bump

Phineas tripped up at the tangible ghost being and fell right on top of him, shocking the ghost up into the air (though his version of "shocked" was very monotone and slow, not very emotional at all). The redheaded boy was flipped onto his back as the ghost stared down at him with large black and white eyes that looked like they may burst into tears at any moment. With a light "bing" sound, Phineas paled at the sight of a red heart popping out of his chest, floating in the air.

Here comes Napstablook.

A/N:

This seemed a good place to end this chapter, and again I must apologize profusely for how long these updates are taking. I didn't expect this crossover to be so…successful. Like, I'm very happy that so many of you like this, even though so far it's just me looking at a let's play of the game and writing down the script…I really need to find a way to put a PnF spin to this.

And yes, Phineas is a bit OOC here…but just a bit. My excuse is that this is probably like one of those Time-Shift episodes, or that Star Wars crossover (which was so awesome, by the way); they were all slightly different because it all took place in AUs within themselves, so they were allowed to be a little different…yes that's a weak excuse, please forgive me.

Anyways, I hope you all enjoyed, and I hope you all had a blessed day/afternoon/evening/night! Carpe Diem, and God Bless you all!
