Almost everyone else fell asleep while Cherry looked like she was trapped in a nightmare. That was until she had enough of the radio and started to smash it.

"Cherry!" Huey complained.

"No... More... Shanties..." Cherry panted.

"Cherry, you're my hero." Dewey told the perky goth.

"Driving! Piloting! Driving... Right..." Launchpad smiled nervously as he seemed to had fallen asleep at the controls until he woke back up.

"Hey, Scrooge, First Mate Dewey here," Dewey said as he soon saw how long they were going by the map. "Your map's got us going the long way. I can probably find a shortcut if you just let me-"

"Ah, ah, ah," Scrooge stopped him right there. "The shortest distance between two points isn't always a straight line."

"And how right you are." Atticus said.

"Okay, but yes, it is, so if you just go-" Dewey tried to help by taking the map.

Scrooge soon slapped the map down with his cane, startling the duckling.

"Uh, let's just leave the map alone." Atticus said.

Launchpad soon fell asleep again until Scrooge hit him awake. "I'm awake!" The pilot panicked.

Dewey soon took the map and seemed to rewrite it. Launchpad looked at the map and continued to follow it.

"You have now just doomed us." Atticus said to Dewey.

"It's called a shortcut," Dewey smirked as he sat back down. "You'll all thank me later."

"I don't like where this is going." Cherry commented.

And where she had a right to feel that way, as there was a Kraken and some fish people and a storm monster.

"Ye kids are the death of me..." Scrooge groaned after all of that was over.

"DEWEY!" Dewey told him his name. "Dewey will be the death of you!"

"No complaint here." Cherry said.

"Can we make a pit stop?" Huey asked as he looked like he needed to pee before opening the door. "I'd use the bathroom, but, it's, uh... Occupied."

A monster snarled as it came out of the toilet, trying to reach out for them. Atticus soon karate chopped the monster away.

"For the love of-It's the middle of the ocean!" Scrooge told his grandnephew. "There are no pit stops."

"How 'bout that conspicuously unmarked tanker?" Launchpad suggested as he saw a boat from the screen on the surface.

"Huh, that's convenient." Atticus said.

"This isn't suspicious at all." Cherry deadpanned.

The submarine soon came up to the surface so that they could make a quick pit stop for Huey. Unknown to them, they were being spotted by one of Scrooge's enemies.

"I sure hope Donald's okay." Atticus said.

"Why?" Cherry replied. "He's not even our father. He's just Huey, Dewey, and Louie's uncle, and we're just forgotten about by our own parents, for all we know, they could be dead."

"No way; if they were dead, I would feel it in my heart." Atticus said.

"You've been saying that for seven years, but nothing has changed..." Cherry replied. "If they were alive, why would they give us up?"

Atticus could only reply in silence.

"That's what I thought..." Cherry replied bitterly.

They soon got out of the bathroom, but Huey had to go back to wash his hands. Scrooge began to wait for him to be finished. Once finished, they all finally returned to the submarine.

"Finally." Atticus said.

"The Drake Barrier Reef," Scrooge informed the others. "Powerful currents combined with rocky terrain make it nearly impossible to navigate, but on that rare occasion when snow falls above the reef, the currents cool, allowing safe passage to-"

The kids all snored until they then suddenly woke up.

"Are we there yet?" Louie asked.

"I hope so because this is boring." Cherry said.

"If ye just let me-" Scrooge tried.

"Look! There that thing is!" Dewey pointed out with glee. "We found it!"

They then soon came into the undersea kingdom.

"No way..." Cherry whispered.

"Ooh." Mo smiled.

"Yes, good. Atlantis," Scrooge scoffed. "Ooh! Aah! Thanks for spoiling the moment."

"It's upside down." Atticus said.

"How does that make any sense?" Cherry asked.

"Well, that's a new one." Scrooge commented.

They soon got inside the upside-down kingdom. Scrooge opened the hatch and smiled at the sights as they finally made it to Atlantis.

"Amazing." Atticus said.

Everyone soon came out of the submarine so they could explore Atlantis together, and where Mo saw the inscriptions on one of the walls, telling what happened.

"Well, according to these markings, the Atlantines were so eager to build an epic city of wonders and death traps, they didn't stop to figure out a proper support structure, and the whole thing fell into the sea!" Scrooge educated the others. "Ye kids best stay by the sub while I scout ahead."

"Dewey ran inside after you said death traps and Atticus went after to try and stop him." Mo said.

"Come on, Scrooge, we've got this!" Dewey called out.

"Dewey, be careful!" Atticus warned.

"Oy," Cherry groaned. "He just never learns."

Scrooge soon climbed in after Dewey and the others followed after. Little did they know, they would be given some unwanted company. And where Launchpad had almost been killed.

Dewey crossed his arms as the others came.

"Oh, Dewey, you're okay!" Cherry said. "But what about the traps?"

Dewey pointed up to buzz saws that were technically on the floor, but it looked like the ceiling from their perspective.

"That answers that question." Atticus said.

"Stupid upside-down temple!" Dewey scoffed. "Nothing cool about walking under buzz saws!"

"From now on, don't touch anything." Scrooge told Dewey before walking on.

Dewey kicked a pebble as they walked off. Soon enough, secret doors opened up which brought out hissing snakes.

"Run!" Mo yelled.

Everyone soon ran away from the snakes before they would be attacked.

"Maybe Atlantis was an ambitious first outing." Scrooge told the others as he cracked his back.

"I agree." Cherry said before Mo's cell phone started ringing.

"Oh, hi, again, Mrs. Beakley!" Mo smiled nervously as she answered the phone. "Yeah, we're still at a friend's house! Uh, her name? Sub... Ina... A totally real name for a totally real person!" she then hung up shakily.

"Uh, good try." Louie smiled nervously back to the older girl.

"Launchpad, are you okay?" Cherry asked the fallen pilot.

"Ah, a little snake venom never-" Launchpad babbled before ducking down and babbled before falling on top of Cherry. "Hi, nice to meet you! I'm everybody's friend!"

"Get off of me!" Cherry groaned.

Atticus soon helped get Launchpad off her before seeing Dewey going on his own again. "Dewey?!"

Dewey came beside Scrooge as he pushed a boulder out of the way despite being an old man. Atticus soon went after them. There was a complicated chasm out with a bunch of lasers blocking their path.

"Whoa! Suspension bridge? Chasm? Glowing blue mystical lasers?" Dewey grinned out of excitement. "Classic!"

"I wonder what the death is?" Mo said.

Dewey tried to walk into it until Scrooge held him back with his cane.

"Even a basic death trap has the word 'death' in the title!" Scrooge glared until triggering the laser with his cane which set off flames.

"Oh, so that's what the death pit is." Atticus said.

"I know this is inappropriate, but I smell roast duck." Cherry commented.

"We'll find another route," Scrooge decided. "It's not safe for amateur adventurers."

"And here comes Dewey thinking what he thinks you meant by that." Cherry said.

"That sounds like a challenge, doesn't it, Cherry?" Dewey smirked.'

"Please stop." Cherry begged.

"I have to stretch that is not a challenge." Scrooge told Dewey.

"Is exactly what you say to dissuade the weak of heart from accepting the challenge!" Dewey smirked. "Well, challenge accepted!"

"And I thought Atticus was blind to reality." Cherry face-palmed.

Dewey began to go through the lights.

"There is no challenge!" Scrooge told Dewey.

Dewey began to go through the lasers, but nothing seemed to be attacking him even though he was touching them.

"That's weird." Cherry said before she looked down to see why.

Donald appeared to be down below and was blocking the flames.

"Donald...?" Cherry asked before rubbing her eyes to see if she was seeing things, but she wasn't.

"Come on, Cherry, this is so easy, even you could do it!" Dewey smiled as he walked through the lasers.

"I'll stay right here." Cherry said.

Scrooge adjusted his hat and soon used his cane as a zip-line and hopped long over the lasers on the other side, wowing both Dewey and Cherry.

"Sure, if you wanna do it the easy way." Dewey scoffed.

"Why wouldn't you wanna do it the easy way?" Atticus asked.

"Ya've got to work smarter, lad, not harder." Scrooge advised.

"He's right, Dewey." Cherry said.

"Ugh... Lad?!" Dewey replied in offense. "I don't call you 'Old Man' or 'Scotty McTopHat'!"

"Respect your elders, when you adventure with Scrooge McDuck-" Scrooge replied.

"But I'm not," Dewey glared. "You want me to adventure behind Scrooge McDuck, or wait by the sub! I might as well be back on the houseboat!"

"Because ye have no idea what yer doin'!" Scrooge replied.

"So show me!" Dewey glared. "Give me a chance instead of lumping us all together in the back seat while you drive!"

"I'm not lumpin' ya all together." Scrooge said.

"Oh, really?" Dewey glared. "Which triplet am I?"

"Uh..." Scrooge paused as he didn't seem to know. "It's... Bluey?"

Dewey narrowed his eyes and walked over which made a huge flame shoot up from below, burning the bridge as the others came.

"Wow." Cherry said.

"Oh, fantastic!" Scrooge scoffed to Dewey. "Ye see what I'm talkin' about?"

"How are we gonna get over there now?" Mo frowned.

"Climb down?" Cherry shrugged.

"That might work." Atticus agreed.

Cherry then climbed with the others.

"Remember not to look down, Cherry." Atticus told her.

"Why not?" Cherry replied before looking down and suddenly looked queasy. "Now I know."

"You gonna be okay, Cherry?" Atticus asked.

Cherry babbled as she looked like she was going to pass out. Mo soon brought out a spare bandanna and climbed down and gave it to Cherry to help her not look down. Atticus stuck his tongue out and tied the bandanna around Cherry's eyes.

"Great, now I can't see anything!" Cherry replied.

"Great!" Atticus smiled as he carried her.

"Tell me when we're on the bottom." Cherry said.

"You got it." Atticus smiled as he helped her down.

"Maybe I could just hire some family," Scrooge muttered to himself. "Then they'd have to listen to me."

"Should one of us go with them?" Mo asked.

"I'll go," Atticus decided. "Cherry, you stay here with Mo."

'Atticus is that you?" Cherry asked since she still had the bandanna on. "All I can see is red darkness."

"Yes, it's me, and I'm going with Scrooge and Dewey." Atticus said.

"Okay..." Cherry replied as she tried to touch his face, poking his eyes and had her finger in his nose before patting him on top of the had. "See you when you get back, and be careful, you're my broth-erm... Roommate..."

"You got it." Atticus said.

The two soon split up. Cherry took the bandanna off so she could see normally.

"Did you just call Atticus your brother?" Mo asked.

"STOP TALKING!" Cherry's eyes widened in embarrassment.

"Okay, okay." Mo smirked playfully.

"Wait up, guys!" Atticus called as he came to Scrooge and Dewey only to see what they saw. "Whoa..." And where they saw a group in there.
