(Well okay peeps here's chapter four, sorry it took longer to post! Whoo! And quick note, I know when Lady Rainicorn speaks you can't understand her, but I'm making it so you can. Just because I don't know how to write Lady Rainicorn's language XD)

"Oh my lumpin' god, look at this guy Bubblegum. He is so hot, like totally sizzling," LSP said. She pointed to a green and yellow lumpy model, while she and Princess Bubblegum looked at 'Lumpy Models Weekly'.

"I suppose he is 'sizzling' but lumpy guys aren't really my type," Princess Bubblegum said. "My type are guys who are smart, scientific, can cook, are in shape, like candy, good dancer, and-,"

"Whoa Bubblegum! Three words: standards too high."

"That was just a few qualities," Princess Bubblegum sighed. "But I guess you're right. But now that we're on the subject of boys, Finn was going to come over and help me study on my science test. He was supposed to be here an hour ago."

"Jake was supposed to meet me here two hours ago for a game of poker," Lady Rainicorn then said, peaking her head into Princess Bubblegum's window. "It seems Finn and Jake has stood us both up."

"Psh, that's what you get when you make plans with boys. They always let you down. Brad always let me down. That's why I dumped him," LSP huffed.

"I'm starting to wonder if they're in danger," Princess Bubblegum said, Lady Rainicorn nodding in agreement.

"Well we could use my GPS on my phone to track them," LSP suggested. "As long as it doesn't run the battery down on my phone and junk."

"That's very kind of you Lumpy Space Princess," Princess Bubblegum smiled.

LSP pressed a couple of buttons on her phone then said, "Finn and Jake are on Blue Gem Mountain."

"Oh no! That's where the evil mountain sage lives," Lady Rainicorn exclaimed.

"Well come on girls! We've got some boys to save!" Princess Bubblegum exclaimed proudly. She leaped on Lady Rainicorn's back then helped LSP on. Then the three flew off towards Blue Gem Mountain.

With Finn and Marceline…

Crash!

That was what noise was made when frozen Finn and Marceline hit the ground after falling from halfway up the mountain. There was a loud shatter sound, and ice chunks flew everywhere; but Finn and Marceline were no longer frozen within ice.

"Finn? Are you okay?" Marceline asked, looking for the human boy. She then stopped when she saw Finn on the ground in a crumpled heap. "Humans. I forgot they probably can't survive falling off a mountain." She kneeled down to Finn, and shook him a couple times. He was breathing, but he didn't move. "Oh come on Finn," Marceline sighed, "Wake up."

Finally Finn's eyelids opened, and he whispered softly, "Are you… okay Marceline?"

"I'm fine. How about you, is anything broken?"

"No."

"Good." There was a silence for a few minutes, the only thing making noise were the nighttime crickets. Eventually Marceline said, "Can you get up?"

"If you help me up," Finn replied. She nodded and help stood him up. "Oh no. We fell all the way down the mountain! We can't get back to the top in time!" Finn shrieked.

"Calm down."

"No! I will not calm down! I promised I would help you, I promised I would get you the cure! But now, you're going to die and it's my entire fault!"

Marceline put a hand on Finn's mouth, and locked her serious eyes with his. "Now listen," she ordered, a slight hiss forming, "We are not giving up. We will not be beaten by nerds. We're better than this. So stop whining, and get a grip."

Finn nodded and Marceline took her hand off his mouth. "But how are we going to go up the mountain?"

"There is one way. But I'll only do it if you want to, I won't pressure you."

"Pressure me to do what?"

Before answering, Marceline released a heavy and stressed sigh. "Remember when we first met, and I became a full bat when I fought you and Jake?"

"Yeah."

"Well I can only obtain that form after drinking pure blood."

"What's your point?"

"My point is, is that if I drink from you, I can turn into a bat and fly back up the mountain. It will be faster, but I don't know how far up I'll be able to go."

Finn gulped. Marceline wanted to drink hisblood. Did he even trust her enough to drink his blood? What if his blood tasted really good and she gets carried away and kills him?

Marceline sensed his hesitation. "Never mind Finn, I could never ask you to do such a thing. You are only twelve."

"No! You can drink from me."

"Can I? Do you trust me Finn the Human?"

For one split second Finn wanted to say never mind, because he was scared. But he knew that this was the only way to save Marceline, and the only way he could keep his promise. "Yes."

"You're sure?"

"Yes."

Marceline smiled, and grabbed Finn's neck. Before biting down, she whispered softly, "This will tickle." Then chomp! In just a few seconds Marceline let go, wiping her mouth.

"Hey that did tickle," Finn laughed. "But did you get enough?"

"Of course I did," Marceline smiled. "Now stand back." Before Finn's eyes Marceline transformed into her true form of a huge bat. She grabbed Finn and set him on her shoulder then the two began to fly up the mountain.

We now join Jake who is still fighting an enraged Ice King, and a trapped Burt in a net…

"You! You made me drop my best friend! That's it man, I'm going to-,"

"Oh shut up," Ice King interrupted. "I have no time to waste fighting you." Ice King walked over to Burt and picked up his brother still in the net, then began to go up the mountain.

"No! I will not let you go!" Jake exclaimed. He enlarged himself and pounded a fist against the Ice King! He fell off the part of the mountain he was climbing, and Jake caught him and Burt in his hand. "Now I'm going to squeeze you two like grapes unless you take me to the mushrooms for Marceline," he barked.

"Never!" Ice King shouted. Jake proceeded to squeeze his grip tighter and tighter. "Ah! Okay, okay I'll take you to the mushrooms! Just please, do not harm my beard!"

"Sellout," Burt mumbled disappointingly. Jake started to climb up the mountain, still huge, and still holding the two nerds in his grip.

"Jakey!" a voice then exclaimed.

Jake turned his head to see Lady Rainicorn with LSP and Princess Bubblegum on her back. "Rainicorn! What are you three doing here?"

"I just came along for the ride, thought we could stop by and get chili dogs on the way back," LSP said.

"Ignore her. We're here because we suspected you and Finn to be in danger," Princess Bubblegum answered.

"Well we were in danger, but we finally have things under control," Jake answered. He then gasped. "Oh no! I forgot Finn and Marceline fell off the mountain!"

"They what?" Princess Bubblegum asked. "And what is Finn doing hanging out with Marceline?" She put her hands on her hips.

"Look I don't have time for explanations. I have to get up this mountain; you three are welcome to follow me." Jake continued to climb and the three princesses followed him. It wasn't too long before they reached the top of the mountain- where Finn and Marceline was. "Dude! You're okay!" Jake exclaimed, leaping on Finn happily.

Finn laughed, "Yeah man we're both okay. Marceline drank my blood and got enough strength to-,"

"She drank your blood?" Princess Bubblegum then asked with a sharp tone.

"Princess! What are you doing here?" Finn asked, surprised to see her, LSP and Lady Rainicorn. He awkwardly took a few steps away from Marceline.

"I'm here because you were supposed to help me study, and Jake was supposed to play poker with Lady Rainicorn. Then Lumpy Space Princess used her GPS, and we found out you were here on this mountain. Now what's your explanation?"

"Uh… just chilling."

"He's helping me," Marceline interrupted sharply. "Got a problem with that?"

"No, not at all," Princess Bubblegum replied, "No need to be rude with me."

Marceline half grinned, "No need to interrogate him."

"Can you guys just like, do what you came here to do because the diner that sells chili dogs closes soon, and I'm like, hungry," LSP said, breaking the tension between Marceline and Princess Bubblegum.

"You're right weird grape girl," Marceline agreed. "Let's go Finn."

If I go with Marceline, Bubblegum will most likely be mad at me later. But if I don't go with her, Marceline will be mad. Oh no! I'm caught in the middle! But Marceline's wrath is much more painful than Bubblegum's so I guess I'll follow her. Finn followed Marceline, and the two began heading more into the mountain.

"Hey Jakey, weren't you holding Ice King and Burt captive in your paws?" Lady Rainicorn asked.

"Yeah," Jake answered.

"So, where are they?"

"Oh holy cow! They must've escaped when I set them down to leap on Finn!"

"That's why you need to pay attention," LSP stated.

"I thought my best friend died after getting flung off a mountain," Jake growled.

"Yah, what's your point?"

Jake released a heavier growl, but Lady Rainicorn put a hoof on his shoulder. "It's okay Jakey."

With Marceline and Finn…

"So, uh, do you not like Princess Bubblegum?" Finn asked.

"No, but there are very few people I do like," she answered. Finn was about to ask her if she could try being nice to Princess Bubblegum, but then he saw a patch of purple mushrooms. "My cure!" Marceline exclaimed happily. She ran over and picked off a mushroom.

"You're going to be okay!" Finn exclaimed happily, glomping on Marceline, knocking them both to the ground.

"I haven't even bitten into the mushroom yet you weenie!" Marceline laughed.

Finn began blushing after realizing what he just did. "Uh right."

Marceline lightly shoved Finn off of her and then put the mushroom up to her mouth. When the mushroom was almost to her fang there was a quick sling noise.

"What was that?" Finn asked, looking around.

No answer.

"Marceline? What's your problem?" Finn asked again. He then saw a red and silver object sticking out of Marceline's stomach. The object went back into Marceline, and she fell over- Ricardio standing there with a bloody knife…

"Ri… car… Ricardio…," Finn stammered. "You… you're the one behind this!"

"Of course," Ricardio smiled, licking Marceline's blood off his knife. "Did you really think the Ice King and his nerdy brother could cultivate this plan?"

"Marceline!" Finn shrieked. He grabbed her arms and pulled her a few feet away from Ricardio. Her eyes were closed, and more crimson blood spewed out from where the knife was.

Jake and the others ran in, and were equally shocked. "Ricardio? You escaped Ice King's chest again?" Jake questioned.

"Yep. Aren't I a smart little artery?" Ricardio laughed, his face wrinkling up. "You see Ice King and Burt were merely my pawns. I was the one who fooled Ice King into putting lemonade into Marceline's blood, made the two brothers attack you, and made Ice King think that after drinking a gallon of lemonade Marceline will be human."

"So… this whole time you wanted Marceline dead?" Finn asked.

"Well she's not dead yet, isn't she? She will be, after I rip out her heart. You see, that's what I've been after this whole time, Marceline's heart. I decided Princess Bubblegum's heart was too tame and sweet. But a Vampire Queen's heart is feisty and a natural match for me."

"Hmph," Princess Bubblegum huffed, slightly offended that Ricardio wanted Marceline's heart over hers.

Finn's beginning to tear eyes looked at Marceline. She was in a crumpled heap, a puddle of her own blood surrounding her. "That's it Ricardio… I'm going to kill you!" Finn screamed. He took out his sword, and pointed it at Ricardio. "And I'm going to enjoy it."

"And I'm going to enjoy watching you fail then killing you!" Ricardio laughed.

"Oh my gosh where is popcorn when you need it?" LSP randomly said.

Finn rushed out at Ricardio, swiping his sword down with all his might! Ricardio easily dodged Finn's hard but careless swipe, and jumped up and kicked him in the head. He then punched Finn's throat, and dodged another sword swipe.

"I'll help you dude!" Jake exclaimed.

"NO. This is my fight," Finn hissed.

"Jeez…" Jake mumbled. Finn is really enraged.

Ricardio kept dodging Finn's sword swipes, and between each swipe he managed to fit in a punch or kick to the head or neck. But finally Finn caught on to Ricardio's strategy, and as Ricardio kicked his neck he grabbed the artery, and threw it against the wall. Then all rage was released, when Finn repeatedly punched him left and right!

Finn was about to crush him with his knuckles, when a sharp voice snapped, "Let him go Finn!"

Shocked, Finn turned around to see Marceline standing up her raven hair covering the left part of her face, and the only thing to be seen was the glint in her eye. "Marceline!" Finn exclaimed happily. "Just one more punch and Ricardio is a goner!"

"I know," Marceline replied. Her voice was different, it was more serious, and it lost all playfulness. "That's why I told you to stop. I don't want Ricardio dead."

"Why?" Finn and Ricardio asked at the same time, both of them equally shocked.

Marceline strutted over closer to the two and answered, "Because I love you, Ricardio. You don't need to take my heart out it already beats crazily for you."

"What?" Finn asked, his voice getting choked up.

"Didn't see that coming!" LSP exclaimed.

Marceline picked Finn up and flung him across the room, then picked Ricardio up. "For so long my heart ached for someone as handsome as you," Marceline smiled. "I'm yours."

"That's… excellent news," Ricardio smiled. "I suppose I don't have to rip your heart out."

"Nope." Marceline leaned in to kiss Ricardio. Her lips touched the side of his head.

Shunk!

Suddenly fangs spliced inside Ricardio, and a loud sucking sound was made! A quick moment passed, and Marceline dropped a now dead Ricardio. The Vampire Queen licked her lips satisfyingly, and wiped a drop of blood from the side of her mouth.

"Marceline… you… you were just acting!" Finn exclaimed happily. He glomped her again, this time not caring if others saw. "How? How did you do it?"

"Right before Ricardio stabbed me I ate the mushroom. I'm all better now Finn thanks to you." Marceline hugged him back.

"Oh I see how it is, no love for a dog," Jake said in an offended tone. Finn and Marceline stood up, and then Finn hugged Jake too, Marceline patting his head.

"You're a pretty cool dog," Marceline said, "Thank you for your help."

"Well, you know, I'm just such a nice dog," Jake smiled.

Marceline, Jake and Finn did a quick tight hug, then Marceline let go. "I should get going you guys. Thank you again, I'd be dead if it weren't for you too."

"Bye Marc-," Finn began, but stopped his sentence because the Vampire Queen was suddenly gone. "She left."

"We should go too, it's getting late," Princess Bubblegum suggested.

A few minutes later…

"What do you think became of the Ice King and Burt?" Lady Rainicorn asked. Princess Bubblegum and LSP were on her back, while Finn was sitting on an enlarged Jake.

"Who knows, who cares, they won't bother us anymore," Jake smiled. "Wait a second! Marceline said she'd reward us for helping her!"

"She did reward us man, with friendship," Finn smiled.

"Tch, no way, you two just got ripped off," LSP said. And that was the end of that.

(Thank you all for reading! I really do appreciate it! Hopefully I'll do more fanfics, but until then bye! =D!)
