"There she is, The Jewel of Atlantis!" An older Scottish duck laughed as he took the red jewel and held it above his head.
"Who's that?" Dewey asked.
"Flintheart Glomgold: the poor man's version of me, which, to be fair, still makes him insanely rich." Scrooge informed.
Atticus soon saw Donald held captive with the group.
"Atticus, is it me or is Uncle Donald down there?" Dewey asked.
"It's not just you." Atticus said.
"Come on," Dewey told him. "We gotta help him."
Scrooge looked nervous and followed the boys as they slid down the gold piles.
"Let go of my uncle!" Dewey glared as he looked ready to fight.
"No." Glomgold smirked as he held the jewel in his arm.
"Did you really think just saying 'let go of your uncle' would work?" Atticus asked Dewey.
"I wasn't prepared for that." Dewey admitted.
Scrooge soon came right behind Glomgold from the gold coin pile and tripped him with his cane, making him fall and let go of the jewel. "What're ye doin' here, Flinty?"
"Scrooge, what are you doing here?" Donald asked.
"I told you to keep the kids safe!"
"Ah, they're perfectly fine." Scrooge smirked.
"Oh, yeah?" Donald asked. "Where are the others?"
"Back safe in the room with the fire and the snakes." Scrooge replied.
"WHAT?!" Donald yelped.
"Ah, Scroogy," Glomgold smirked to his rival. "I see ye know my newest employee."
"Your new job is with Scrooge's sworn enemy?!" Atticus glared at Donald.
"I can't keep track of all his sworn enemies!" Donald defended.
"Now, now, Donald has been a model employee, and an excellent prisoner.." Glomgold smirked.
"Yeah!" Donald folded his arms until he realized what he just said. "Wait, what?!"
"You were using him as a prisoner?" Atticus asked.
"Hirin' my own nephew in order to use him against me?" Scrooge frowned in betrayal. "Now, that is good planning."
"It truly is." Atticus said.
Glomgold and his crew soon left with the jewel before chucking Donald away like he was useless to them.
"Have fun being the second richest duck in the world for the next five minutes." Glomgold laughed at Scrooge as his henchwoman threw her sword against the ceiling to access a trap.
"Oh, wow." Atticus said.
The doors soon closed. A crystal lit up and the area was soon flooding with water.
"I'd like to point out that this trap was not my fault." Dewey said.
"Oh, no, oh, no, oh, no!" Atticus panicked and hyperventilated. "We're gonna drown!" He began to run to the closest floating object.
Meanwhile with the others...
"Junior Woodchuck Rule 841: There's always another way around." Louie told the others.
Cherry looked around as she finally got to touch the ground and looked to Mo as her cell phone rang.
"No, no, no!" Louie panicked.
"Oh, look! Uncle Hampus is here, and he only speaks Swedish," Mo smiled nervously as she answered the phone. "We don't want to be rude, so goodbye?"
Cherry face-palmed and shook her head. "And you're done." She then groaned.
"Yeah, you're never gonna be able to back up that lie." Louie added.
Launchpad soon took the phone and babbled to Mrs. Beakley which covered up the lie for Webby and Mo. They soon heard Glomgold's laugh. Everyone turned to see the fat Scottish duck with the giant jewel.
"Take 'em down." Glomgold told his crew.
"This could be a problem." Cherry commented.
Meanwhile, back with Atticus, Scrooge, Dewey, and Donald...
Atticus kept trying to avoid touching the water as he had a serious case of aquaphobia.
"We gotta stop the water!" Dewey told the others.
"Oh, yeah, and how do we do that?" Atticus asked.
Donald tried to plug up one hole with gold only for the coins to smack him in the face until his tailfeathers got stuck, he then poked the other holes with his finger and webbed feet and glared to Scrooge and Dewey. "I knew it! I knew I couldn't trust you with the kids!"
"Not the time, Donald!" Scrooge told him.
Atticus kept trying to avoid the water as the levels were rising while Scrooge and Donald argued.
"Crazy old man!" Donald glared at his uncle. "All you care about is your next adventure. This is the Spear of Selene all over again!"
"The Spear of Selene?" Atticus asked out of confusion.
"Stop!" Dewey tried to get Donald and Scrooge to stop arguing as he floated on a chest. "Scrooge was trying to keep me out of trouble, but I was so caught up in-Why is there a lamp on the floor?"
"What?" Donald asked out of confusion.
They soon looked up with Dewey.
"What? Atlantis is upside down," Dewey said. "That means that lamp was supposed to be on the floor surrounded by all this treasure."
"That's right." Atticus nodded.
"Thatta boy, lads, keep going." Scrooge said.
"But why would you surround that thing with treasure unless-" Dewey began.
"That's the real Jewel of Atlantis!" Scrooge, Atticus, and Dewey realized together in unison.
"I bet that if we surround this entire room with water, then we can float all the way to the top and get the jewel free." Atticus smiled.
"Ye might have somethin' there, boy." Scrooge smiled back to him.
"Donald, you need to let the room flood in with... Water." Atticus gulped.
"That's crazy!" Donald replied out of concern. "Besides, Atticus, you never liked swimming, you always think you're going to drown."
"I know, but it's the only way we can get to the Jewel of Atlantis." Atticus said.
The two looked to each other long and hard. Donald soon took a deep breath and unplugged the holes so the water would fill up.
"Here it goes..." Atticus sighed shakily before he tried to embrace it, and where he soon had help with the water.
Dewey hopped up and latched onto the jewel once the water was high enough. Scrooge, Dewey, and Donald struggled to free the jewel as it felt snuggly stuck. Atticus soon helped them get it free and with his strength included, it would be easy. POP! The water was soon draining out once they caught the jewel.
"That wasnt' so bad..." Atticus gasped and panted once the water drained out and he held the jewel.
"You conquered your fear!" Dewey smiled.
"Yeah... I guess I did!" Atticus smiled back.
"We better go and check on the others." Atticus said.
The others were soon forced to fight against Glomgold and his crew. Cherry backed up nervously as she couldn't fight on her own. Luckily Mo had her back.
"How'd I do, Mo?" Webby smiled.
"You are doing just fine, Webby." Mo smiled back, proudly.
"We nearly forgot about those guys." Atticus said.
"Oh, yeah," Donald added. "Huey, Louie, Cherry! ...Are doing okay."
Louie and Huey smiled as they high-fived each other in success of the foe they faced. Mo and Webby were able to beat one of the foes.
"Wait... Where's Glomgold?" Scrooge asked as he noticed someone missing.
'Hey, team,' Glomgold's voice said through a walkie-talkie. 'Wanted to thank you for keeping Scrooge's kin busy while I escape with the jewel and blow up Atlantis with my most hated rival inside.'
"That's low." Cherry said.
"But I thought employees were greatest treasure of all!" The wolf frowned.
'Don't be ridiculous!' Glomgold scoffed. 'Treasure is the greatest treasure of all. That's why it's called treasure! Glomgold out!'
"I suggest we run back to the sub." Atticus said.
"We haveta go!" Scrooge agreed as they soon ran.
The place was soon beginning to crumble once they made it back to the submarine, and where even Glomgold's team came with them. Atticus smiled as he looked out the windows to see the ocean, not scared of it anymore, much to Cherry's shock.
"That was some smart thinking." Scrooge smiled at Dewey and Atticus.
"Yeah, adventuring's fun." Atticus smiled back.
"I think ye just might be adventurers yet," Scrooge nodded. "Dewey and Atticus."
