After a nice, hot shower and borrowing a pair of clean pajamas, the sleepover at McDuck Manor was back in full swing.

Rosie faced Duckworth and took a deep breath. The ghost gave her a nod of approval.

Webby put her hand on Rosie's shoulder. "Go on, Rosie. You can do it."

With determination sparking inside her, Rosie braced herself. "Alright, Duckworth. I'm ready."

Duckworth floated to Rosie and passed right through her. Rosie went tense as the ghost phased all the way through. It felt like a gentle breeze of cold wind.

"Whoa!" Rosie gasped. She patted her chest, the cold feeling lingering. "He really passed right through me!"

"I know! Isn't it cool?!" Webby said, very giddy.

Rosie shivered, rubbing her arms. "It's cool alright." She managed to smile despite the otherworldly chill. "But still, this is amazing! A real ghost! And he's a butler! Is there anything else about this place I should know about?"

"There's me!" a voice called out. Rosie turned and saw a duck wearing a pilot's outfit. She walked into the living room, Rosie noticed that one of her legs was mechanical.

"Hi! You must be Rosie!" She took Rosie's hand and gave it a shake. "I'm Della Duck! Huey, Dewey, and Louie's mom!"

"Nice to meet you, Ma'am." Rosie said politely. She couldn't help but let her eyes travel to Della's leg.

Della saw her guest staring. "Oh! That!" She laughed. "Just a leg I put together from rocket parts when I landed on the moon."

"You were on the moon?!" Rosie said in awe.

"Yep." Della nodded. "It all started a decade ago before my boys were hatched..." Her eyes got misty before she blinked in realization. "Wait! Where are my boys?"

"Oh, no!" Webby yelped. "The guys took off looking for Rosie! They thought she left!"

"Uh-oh! Well, we better go find them!" Rosie said.

But before anyone could go anywhere, there was a knock at the door. "I got it!" Della rushed to the door. But before Della could answer the door, it was kicked open!

Reacting fast, Della jumped back and took a battle stance as Buster Beagle swaggered in.

Webby, Rosie, and Duckworth were watching from the living room. "Is that Buster Hunster?! What's he doing here?!" said Webby.

"Ohhhh...no..." Rosie moaned. "I Just remembered...while I was hiding in thr pantry, I called Buster over to...exterminate all the ghosts in the mansion..." She sunk when Duckworth and Webby glared at her. "But don't worry! I can make this right! I'll just tell him to leave and there's no ghosts! Piece of cake!"

But Rosie stopped when the Beagle Boys came through the door with Huey, Dewey ane Louie tied up and held captive by Bouncer.

"MY BOYS!" Della screamed before she growled, her face was turning red.

"Don't try anything, lady or the brats get it!" Buster warned. "You want them in one piece? Then give us the deed to Duckburg!" He smirked. "And thanks for opening the gate for Buster Hunster!"

"No need for your TV name, Buster." said Big Time. "Just go by your real name, Buster Beagle!"

Webby gasped. "Buster Hunster is a Beagle Boy?!"

Rosie started to panic. She started to clutch her hair. "Oh, man! This is all my fault! This is all my fault!"

"WHOA! Easy, Rosie! Calm down!" Webby coaxed. But Rosie was too far gone. She grabbed Webby by her shirt.

"I just let a bunch of criminals into your house! Don't you tell me to CALM DOWN!" Rosie shrieked. "I gotta make this right! I brought them here, so I'm gonna get rid of them!" Rosie looked around and saw a glowing sword mounted on the wall. "This'll do!" She grabbed the sword.

"NO! NOT THAT!" Webby screamed. "It's the Deus Excalibur!"

But it was too late. The magic sword began to move on it's own, taking Rosie with it. She screamed as she soared out of the room and toward the Beagle Boys.

"What the-?!" Bouncer dodged just as the sword passed his head. The beagles scattered as Rosie flew around the room.

Della saw her chance and attacked. She skillfully kicked Bouncer right up the jaw with her metal leg. Bouncer fell over, out cold.

"LOOK OUT!" Rosie screamed. The sword zipped past the triplets, cutting their ropes. "HOW DO YOU STOP THIS THING?!"

"It won't rest until it's target is slain!" Huey yelled for Rosie to hear.

"BUT I DON'T WANNA KILL ANYONE!" Rosie yelled back. The sword was about to skewer Burger Beagle until two hands easily caught the blade.

"I got this!" Della took the sword. "Alright! Who wants a piece of Della Duck?! Do I have to take a piece of each of you?!"

"Scatter! Let's find the deed and get outta here!" Big Time, Burger, and Buster went in different directions.

Big Time tried to enter another room, but Webby came in his path and tackled him, beating him relentlessly.

Burger tried to head further into the manor. But Mrs. Beakly came charging in and sucker punched the crook hard across the face

Buster was almost up the stairs until a giant, shadowy demon with a horned skull and red eyes loomed over him. He gasped in horror as the horrid phantom snarled. "Wha-?!" He started to tremble. "B-B-But g-ghosts aren't real!"

"GET. OUT!" Duckworth roared. His booming voice sent Buster tumbling down the stairs. As quick as a flash, Duckworth used his ghostly powers to make each Beagle Boy vanish from the room.

Rosie stood there, her jaw hanging open. "Where'd they go?!"

Duckworth reappeared before Rosie. He was back to his ghost form. "From whence they came, my dear. From whence they came."

Huey, Dewey, and Louie rushed to Rosie. "Rosie! Are you alright?!" asked Huey. "Did the Deus Excalibur hurt you at all?!"

"Duckworth didn't scare you half to death, did he?!" asked Louie.

"Which one of us is going to be your boyfriend?!" Dewey asked excitedly. His hands flew to his mouth. Huey and Louie froze.

"B-Boyfriend?!" Rosie sputtered. "What are you guys talking about?!"

"The young masters have been competing for your affection, Miss Rosie. Hence their erratic behavior this evening." Duckworth explained.

Rosie blinked. "Ohhhhh, right." She looked at the boys. "Um, guys. I'm flattered, but, I really don't need a boyfriend. I just wanted us to be friends. Just friend friends." she said honestly. "I mean, just because I'm a girl and you're guys doesn't mean I'm looking for romance. I'm only ten years old."

Huey, Dewey, and Louie felt very foolish.

"You're right, Rosie." said Huey. "You weren't looking for a boyfriend. You just wanted...friends."

"We're really sorry about how we've been acting." Louie rubbed the back of his head. "Guess we still have a lot to learn about girls."

Rosie laughed. "That's for sure. But it's cool." She smiled. "So, guys, the night is still young. Wanna get this sleepover back on track?"

"You bet!" Dewey fist-pumped. "What first?!"

"How about a ghost story?" Rosie suggested. "Duckworth, do you know any good ones?"

"Indeed. Might I suggest telling my most frightful tales in the attic for spooky atmosphere?"

"YEAH!" Webby and Rosie cheered.

The boys looked rather nervous.

"What's wrong, guys? Not scared of ghosts, are you?" Rosie joked.

"NO!" Huey, Dewey and Louie protested. The kids followed Duckworth upstairs to the attic for some ghost storytelling.

The next morning after a delicious breakfast, Rosie packed up her things as she was ready to return home. "Thanks for everything, you guys! This was the best sleepover ever!" She hugged her four new friends. "I still can't believe Buster was really a Beagle Boy! And I wasted all this time watching his dumb show!"

"Yeah, well, he and his brothers won't be coming back here anytime soon!" said Dewey.

"You're welcome back to the mansion anytime, Rosie." said Mrs. Beakley.

"Thanks, Mrs. B." Rosie said.

Duckworth approached Rosie with the crystal ball in his hand. "I found this in Master Louie's hoodie while doing the laundry."

"Louie!" Huey, Dewey, and Webby scolded.

"What?! I was gonna give it back!" Louie fibbed.

Rosie's eyes widened. "Oh! The crystal ball thingy! Webby told me this thing made you appear when were playing fortune tellers, Duckworth!"

"This crystal ball has the power to contact spirits as well as summon them." said Duckworth. "How did you come across this bobble?"

Rosie looked at the magic artifact. "Honestly, I just thought that was a cheap paperweight I found on...my dad's desk. But I think you guys should keep it."

"Good idea." said Duckworth. "I'll keep this in a safe place." He gave Louie a salty look. "This might be too dangerous for you."

Louie shrunk back. "Anyway...come back anytime, Rosie

"I sure will!" Rosie hugged Webby. "Thanks for everything, you guys!"

"No problem!" said Webby.

After saying her goodbyes, Rosie left McDuck Manor and walked all the way to Glomgold Industries.

Rosie came out of the elevator and was greeted by the friendly face of Zan Owlson. "Hey, Zan."

"Hey, Rosie." Zan welcomed with a friendly face. "How was the sleepover?"

Rosie opened her mouth to answer, but an angry Scottish voice cut her off.

"Who cares about that?!" Stomping toward Rosie was Scrooge McDuck's arch nemesis; Flintheart Glomgold. "What did you find out at McDuck Manor?!"

Rosie shook her head. "Nothing, Mr. G."

"WHAT?!" Flintheart yelled. "I plucked you out of the orphanage and secretly adopted you to spy on McDuck and you say you found NOTHING?!"

"You WHAT?!" Zan asked in shock.

"Relax, Mr. G. I just made friends with the kids. It's gonna take some time before I can dig up some real dirt on Mr. McDuck." Rosie explained calmly. "Trust me, I practically got them eating sugar cubes out of my hand."

"Alright, keep up the good work." Flintheart blinked. "By the way, have you seen the Specter's Stone? It was on my desk yesterday! I was hoping to use it to summon spirits to haunt McDuck!"

Rosie tensed up. "Um...no idea. Never heard of it." she lied.

Flintheart sighed. "At least I still have my spy." He laughed in his throat, stroking Rosie's head. "Watch your back, McDuck!" He kept laughing as he retired to his office. Rosie went to the elevator, but Zan stopped her.

"What was that all about?!" asked Zan.

"Huh. Mr. G didn't brag to you about his evil plan?" said Rosie. "See, Mr. G only adopted me in secret so he can use me as a spy to get some dirt on Mr. McDuck and his family."

"And you're okay with this?!" Zan blurted out.

"Of course. Don't worry, Zan. Just relax and go along with the plan. Listen..." Rosie leaned in and whispered something into Zan's ear.

When Rosie pulled away, a look came upon Zan's face that was understanding but dubious. "Alright, Rosie. I won't ruin the plan. I just hope you know what you're doing. Mr. Glomgold can be..."

"I know how he can be, Zan. But don't sweat it. I got this in the bag. See you later." The elevator door closed took Rosie to her room on the top floor. When the doors opened, Rosie's eyes twinkled. Thanks to her wealthy "father", her bedroom was something out of a fairy tale. She had a pink canopy princess bed with a diamond chandelier hanging over it. Lavish white furniture, soft pink carpeting, and a window seat that looks over all of Duckburg. And to top it all off, a huge flat screen TV and was placed perfectly in front of her bed.

It was the room of her dreams.

Rosie smiled to herself. "Working for a rich dude has it's perks." She hopped onto her bed and sighed.

'There's more going on at McDuck Manor than I expected. Ghosts, criminals, haunted swords with minds of their own.' Rosie said in her head. 'Glomgold doesn't need to know a thing. I finally got the life I want.'

Rosie took out her brand new phone and looked at the happy selfies she took with her new friends. There were selfies of her and Webby and the boys wearing monster make-up. She even took a monstrous selfie with Duckworth.

'I made the coolest friends I could ever find. And there's a world within a world revolving around Webby, Huey, Dewey, and Louie.'

Rosie smiled to herself. "I can't wait for the next playdate."
