Meanwhile, back with Launchpad and Lionel...

"The ice fever in final stages," Launchpad told himself, but in a hot tub. "Must stay warm."

"I give up." Lionel rolled his eyes. He soon saw Louie and Jessica.

"Uh, Launchpad?" Louie glanced at the pilot.

"So... Warm..." Launchpad told himself.

"LAUNCHPAD!" Louie called out, removing the earmuffs.

"Louie, is that you?" Launchpad soon smiled before touching the young duckling's face and climbed out of the hot tub. "Stay calm, little buddy. We need to find a way off this mountain before ice fever takes us both."

"He does realize he's no longer on the mountain, right?" Jessica asked Lionel.

"I'm afraid not," Lionel replied, floating over to her with his towel. "He's gone Looney Tunes!" he then smiled to the invisible fourth wall. "A registered trademark from the Warner Bros. Federation!"

"Okay, but why does think that Ice Fever is real?" Jessica asked.

"Beats me," Lionel replied to her. "He saw some guy before the others went mountain climbing. Must've been a con artist if I had to guess."

"Louie, you know what this means, right?" Jessica asked.

"Launchpad's gone off the deep end?" Louie guessed.

"Okay, LP, who gave you this stuff?" Lionel then asked.

"I dunno, but he sold me this stuff and told me about ice fever." Launchpad replied.

"Standard double snake oil. I see how it is," Louie soon glared. "Well, no one cons my family but me!"

"Yeah!" Jessica beamed before giving him a look. "Wait..."

"That came out wrong." Louie said.

"Yeah, it really did." Jessica told him.

"Our combined body heat will save us both," Launchpad told Louie, hugging him in the blanket. "Soak in the wetness of my sweat!"

"Ew! So much wetness! Ew!" Louie grimaced.

"Lionel, you can join back with the others; me and Louie got this." Jessica said.

"Hmm... You sure?" Lionel asked.

"Yeah, we'll talk later." Jessica replied.

"Okay," Lionel said, snapping his fingers in his own winter gear. "I should probably keep an eye on 'em anyway." he then teleported himself to wherever the others were right now.

Meanwhile with the others...

"At last! After all these years, the summit of Mount Neverrest!" Scrooge beamed as Lionel soon appeared, floating beside the group, though Cherry glanced back at him before looking above with the others as they soon came to a stop. "We're in the clear now, kids! Ha-ha!"

A part of the mountain soon fall off.

"Well, that's not very good." Cherry commented.

Scrooge let out a weak chuckle and walked off with most of the others.

"Okay, that's it," Atticus glared as he had enough. "I'm putting my foot down; we can't keep going, because if we try to climb the mountain, it'll come crashing down."

"Good luck telling Scrooge that," Cherry deadpanned slightly. She soon saw that Scrooge did hear Atticus. "Oh, hi, Scrooge."

"Atticus, we must keep going." Scrooge told the boy.

"No." Atticus said.

"Excuse me?" Scrooge asked.

"No, this is too risky." Atticus told him.

"I have a job to do." Scrooge replied.

"Endangering all of us?!" Atticus glared.

"Atticus is right, this is too risky." Huey added.

"Don't you go ninny on me, lads!" Scrooge told them. "You'll never get your cartography badge with that attitude!"

"I don't care!" Huey replied. "We have to turn around now!"

"Now!" Dewey and Webby smiled.

They soon heard rumbling.

"You already beat Mallardy," Atticus glared at Scrooge. "Isn't that enough?"

"No! We'd be daft to give up with the peak in our grasp." Scrooge replied.

"Do you honestly think that reaching the top is more important than safety?!" Atticus glared at Scrooge.

"It's not giving up," Huey added. "It's just having common sense."

"For the last time, nothing bad is going to happen!" Scrooge told them.

"Uh, guys?" Mo spoke up.

They soon felt some rumbling.

"Ooh, how I wish that were my stomach." Lionel frowned.

Webby and Dewey yelled out as they soon fell off.

"WEBBY!" Mo shrieked.

"DEWEY!" Atticus and Cherry cried out.

"Kids!" Scrooge yelped.

"Webby! Oh... What am I gonna tell Mrs. Beakley?!" Mo frowned.

"Her granddaughter is gone?" Cherry bluntly replied.

"This is serious!" Mo told her.

Cherry shrugged. "What're we gonna tell Donald about Dewey?"

"Yoo-hoo!" Webby's voice called out.

They soon all turned around to see Webby and Dewey on top of them in the mountain.

"How did you guys get up there?!" Atticus asked Dewey.

"I don't know!" Dewey shrugged.

Scrooge felt very overwhelmed and confused before holding his head. "Maybe Launchpad was right about ice fever."

Cherry narrowed her eyes and soon began to make a snowball and threw it off the edge.

"What are you-" Dewey asked her until the snowball hit him in the head from behind. "Ow! What?"

"How in the world?" Mo asked.

"Wormholes!" Lionel beamed.

"What?" Cherry asked flatly.

"He's right!" Huey smiled, checking his map. "This mountain is covered in some kind of mystical dimensional doorways that have been randomly zapping us around the trail all day! Between the fog and the snow, we didn't even realize it! That's why my map didn't make sense!"

"Of course!" Atticus smiled back.

"Hoots, man! A mountain protecting its peak with portals!" Scrooge sounded amazed. "Neverrest, you beauteous beaut, you never cease to amaze," he then looked back at the boys with a smirk. "And you wanted to turn around!"

"Don't even." Atticus narrowed his eyes with Huey.

"We have to find a way to get them down." Mo said.

Dewey soon took a look around.

"What're you doing?" Webby asked him.

"We're at the top of a magical mystery mountain!" Dewey told her. "I gotta find my sled, like, now!" As he walked on ahead, a wormhole took him farther away.

"This is REALLY weird..." Cherry said.

"I know! Isn't it just... Just... Awesome Sauce?!" Lionel grinned.

"Uh... Yeah..." Cherry blinked from his reaction.

Dewey and Webby soon noticed that he walked through a wormhole. The two began to have fun, messing around with the wormhole.

"I feel nervous seeing them up there." Mo said, feeling something wrong would happen.

Pieces of the mountain started to fall off from Dewey and Webby's messing around.

"Webby, be careful!" Mo cried out.

"The more you zap around, the less stable this ice becomes!" Huey added.

After hearing this, Dewey and Webby stopped zapping around.

"Good..." Cherry sighed in relief. "Maybe they'll relax now."

"Hey! My sled!" Dewey called out as he looked up.

"I'll get it." Lionel said.

"You do that..." Cherry replied.

Lionel soon poofed away and came up to the sled, taking it, and came to give it back to Dewey and Webby. "We're thinking with portals just like in that one video game." He then smirked.

"Nice." Dewey smiled.

Scrooge began to look down to the edge.

"Okay, come down before you get hurt!" Cherry told Dewey and Webby.

"But please be careful!" Mo added.

Scrooge soon appeared beside Lionel as he gave the sled back to Dewey and Webby.

"He's gonna get to the top using the wormholes." Cherry sighed.

"I doubt it'll work." Atticus said.

"I'm gonna do it! Mount Neverrest, consider yourself conquered!" Scrooge laughed as he jumped to the top, but came out of a wormhole, taking him back to where he was. He then began to try again, but no matter what, he couldn't make it to the top of the mountain. "Conquered! Conquered! Conquered!"

"Give it up already!" Atticus told him.

The mountains began to crack along.

"Just stop! There's no way to reach the top." Huey told Scrooge. "The mountain won't let you! Let this one go!"

"Look how far we've come!" Scrooge replied.

"Farther than anyone has ever made it, isn't that enough?" Huey frowned.

"I will not be the Neverrest Ninny for another 75 years!" Scrooge glared.

"No one has used the word 'ninny' in 75 years!" Atticus glared back.

Scrooge looked to the mountain and backed at them, a bit somberly.

"Rule 727: 'Sometimes the bravest thing an explorer can do is walk away'." Huey quoted before dropping the badge, and it was soon zapped away by a wormhole and where it ended up close to Scrooge.

"I think he needs that as a lesson." Atticus remarked to himself.

Scrooge looked to the kids and the badge and soon let the badge flow away to the wind.

"Okay, now they really should get down from there." Cherry said.

"Don't have an anxiety attack." Mo said.

"I can't help it!" Cherry replied. "Huey, Dewey, and Louie are like my little brothers!" Her panicking voice seemed to echo, and where it caused the rest of the mountain, except the top to come crashing down.

"Eeeeek..." Cherry shivered a bit. "Okay, maybe I was a little too insensitive to Mo about Webby. Just please let them be okay!"

"Now?" Webby asked Dewey.

"Now!" Dewey told her.

"Here we go!" Lionel cheered.

And soon began an epic snow sledding ride down from the crumbling mountains. And where everyone was on the sled.

"Whee! Put your hands up!" Lionel laughed as he had a ball.

"Hang on, kiddos!" Scrooge told them.

"Way ahead of ya!" Mo replied.

Lionel laughed as he had fun like he was an amusement park while they sledded down to the others. The others soon began to run down the hill with Huey as it was now an avalanche, and even Bunny Rock got included. Cherry panted from the running, and Atticus soon carried her so that they could keep going and she wouldn't get left behind.

"Okay, Cherry, in a bit, I'm gonna jump, so hold on when I say 'go'." Atticus told the girl.

"Okay!" Cherry replied.

"Okay, here it comes, ready, set... Go!" Atticus told her.

Cherry soon held on as tight as she could and Atticus soon jumped to get them both on the sled, and which he was successful.

"Phew." Cherry sighed once they made it onto the sled together.

"I got you, Cherry, I got you." Atticus coaxed to his friend.

Dewey soon held out his hand for Huey, once his brother held his hand, he soon pulled him onto the sled with them.

"Everyone on the sled?" Atticus asked.

"I think we're all good..." Lionel said before counting to check.

"Great." Mo said.

The others sighed in relief until they panicked, seeing a ledge coming up as they slid off the hill.

They soon appeared elsewhere from the wormhole, letting them sled peacefully at first.

"So this is what people do on Christmas, huh?" Lionel commented.

"Most families." Cherry shrugged.

They were soon on top of Bunny Rock with a long way to go.
