DuckTales!

DuckTales! It's a Special Episode based on the First episode of DuckTales! (2017 Remake)

Plot
At the Duckburg harbor, Gordon is preparing for a job interview while Percy and James enthusiastically help him get ready, which ends up causing messy results. After he discovers that the babysitter is unable to make it, presumably due to the boys giving her a new address, and Thomas destroy accidentaly the Turnbable without him around, Gordon reluctantly takes the Engines to Duckburg's billionaire-adventurer Montage McDuck, much to the engines' excitement.

Meanwhile, a sulking Duck is attending a business meeting with his advisors listening to his company's current stock. Once the meeting adjourns, Duck has his chauffeur, Launchpad McQuack, drive him by his money bin before heading back to McDuck Manor. However, he runs into Gordon and the boys at the entrance. After a moment of tension between Duck and Gordon, Gordon introduces engines to Duck as their formerly estranged uncle. While the engines are amazed at the revelation, Gordon instructs Duck to watch over them while he attends his job interview. Before leaving, Gordon cryptically stipulates that he keeps the engines out of trouble.

Inside the mansion, the triplets immediately hound their uncle with questions about the fantastic tales the billionaire was known for. Aggravated by their questions, Duck has his maid Bentina Beakley escort the engines to another room and locks them in there, with Beakley giving the trio a bag of marbles that they will return upon their departure, and informs then Duck will know if one is missing. In a dark room, Duck dusts off a display case housing his old diving suit. Unwilling to put up with Duck's distance, Thomas tries to break out of the room bashing the doorknob off with the bag of marbles, but the three are suddenly captured by a engine named Rosie, initially believing that the triplets were Diesels. She introduces herself as she befriends the triplets, and explains that she was researching Clan McDuck as Duck along with Gordon were once famous adventurers. Despite Percy's claims that their family is mundane, Rosie dismisses this and offers to take the engines to the manor's "wing of secrets". Meanwhile, Duck reflects nostalgically on his past endeavors and remarks to Beakley how discontent he is due to the past problems he had with his family over his years of obscurity. Eventually, taking his nephews' inquisitive remarks to heart, he decides to take the engines to the lost City of Atlantis.

As the engines enter the wing, they discover it is filled with artifacts and statues. James proceeds to plaster everything with blank green sticky notes, claiming he is calling dibs. Rosie halts him from touching the Thanos' Infinity Gauntlet, since any organic matter it touches, It is desintegrated, but Percy calls it a maybe. Although the boys become increasingly convinced that the rumors behind Duck were true, Thomas comes across an old portrait depicting Duck fighting alongside Gordon; because they doubt Gordon was an adventurer, they conclude that Rosie's claims were false. Just then, the engines stumble across a few artifacts that release ancient horrors - Captain Peghook the pirate ghost, the Deus Excalibur, and the Headless Man-Horse - that proceed to team up and attack them, with the Deus Excalibur and the Headless Man-Horse each hiting the Gong of Pixiu. Duck arrives on the scene and defeats the ghosts one by one. Despite the children's relief, Duck reveals that the wing was actually a garage, and is furious over the trouble they have caused while displaying regret towards spending time with his nephews. When Thomas mocks how spiteful Scrooge is towards family, an infuriated Duck tells them to leave.

In his anger however, Duck accidentally hits the Gong of Pixiu, and when the statue holding the gong crumbles Duck surmizes that the kids hit the gong two times already. This releases the gold-hunting dragon imprisoned inside it. The Pixiu then flies off towards the largest gold storage in Sodor, which happens to be the Money Bin. Duck grabs on the dragon to slow it down, but not before ordering the enginess to return to their rooms; on ground, the engines feel guilty for their behavior and decide to help Duck. With the help of Launchpad, they rescue Duck just as the dragon shakes the duck off. As the engines swing him down from the aeroplane, Duck manages to touch the dragon with Thanos' Infinity Gauntlet before it can reach the gold, turning it Desintegrated. Back on the ground, Duck berates the nephews for disobeying him, since their antics released the evil entities from his artifact collection and almost killed him, and despite being angry at the engines at first, Duck admits to the engines that he enjoyed it and is motivated to restart his adventurer career. His spirit rekindled, Duck decides to take them all on a mission to find the Lost Jewel of Atlantis, an immense source of power. Elsewhere, Gordon has his job interview and is hired as a sailor by Duck's rival, Diesel 10, who also seeks the jewel.

During the voyage undersea, Thomas is irritated about Duck's cautious measures on keeping the group out of danger. He comes to believe that Duck doesn't consider the engines, particularity Thomas, as explorers. On the water's surface, a tanker carrying Diesel 10's group (consisting of himself, Gordon and mercenaries Gabby, Hackand Slash) detect Duck's submarine. Gordon discovers that Duck and the engines are on board the submarine, and threatens to punish them once he finds them; 10 misinterprets Donald's words for actual threats and agrees to this plan as he decides to follow the submarine down to the city. After passing through several underwater obstacles due to Thomas tampering with the map, Duck's submarine reaches Atlantis. They discover that the city is upside-down since the city had collapsed on its own support structure, and begin exploring.

When 10's group arrives after them, Gordon realizes that 10 could kill his friends when he gets the chance. He secretly hinders the attempts on their lives and convinces 10 to spare Duck so that they can torture him later, to which 10 agrees. Due to Thomas' overeagerness, he tries to cross a bridged boobytrapped with flame throwers as Gordon tries to protect him from ruins' trap. When Duck tries to go after him, they end up getting separated from the others as the flames finally burn the bridge apart. They watch 10 overhead reach the chamber and claims what appears to be the Jewel of Atlantis.

Thomas notices Gordon within the group and confronts them believing that 10 had his as a hostage. Duck pins down 10, and after a brief exchange 10 admits that he was using Gordon to get close to Duck and has his henchmen hold Gordon hostage, forcing Duck and Thomas to let the evil Diesel to escape with the jewel. 10 then has Gabby throw her sai the 'top' causing the room to flood with water as the trio are trapped inside to drown. As Gordon futilely tries to plug the holes, he blames Duck for recklessly endangering his nephews to rekindle his adventuring spirit, comparing their situation to a past incident with the Spear of Selene, to which Duck denies responsibility. Thomas realizes his overeagerness has endanger Duck and Gordon and tries to apologize for his action; he then realizes that the jewel 10 took was fake as the room was still fully powered and sees the real jewel is right above them. Thomas grabs the jewel with Duck and Gordon's help, stopping the water flow. In the commotion, 10 leaves his lackeys behind to escape with the jewel. The trio regroups as they find the rest of the team defeating 10's henchmen. In his submarine, 10 fires missiles at Atlantis, causing the city to crumble; however, everyone (including 10's henchmen) escape in Ducke's sub before Atlantis is destroyed. Back in Sodor, 10 is attending a meeting with the press over how he has uncovered the Jewel of Atlantis. However the press is interrupted when Duck arrives with the real jewel and offers to use it as a power source for the city. The media celebrate Duck's return to adventuring, while 10 suffers the curse of his jewel by getting caught by a massive tentacle.

Seeing the engines' responsibility and how well the engines bonded with their uncle convinces Beakley and Gordon to allow the children to accompany Duck on further expeditions. At that moment, Gordon's shed explodes due to Thomas' earlier mishap, so Duck offers to let them all move in McDuck Manor. While Gordon has his boat moved into the manor's pool, Duck and the engines reorganize the garage's artifacts. Thomas comes across the portrait from before and notices a tear covering a female engine fighting with Duck and Gordon in the scene, whom Thomas recognizes as his mother.
