HydroWorld: Hydroplanetary Adventures - Season 1, Episode 47: "Roguetopia: The Greatest Flying Kingdom To Ever Sail The Skies"

Bounder Bully Regis Saunders teams up with Hydrohaus to establish a newly-developed massive, flying kingdom that will lure all walks of life into the Rogues' long-time objective of ending HydroWorld once and for all.

Once construction finishes, the Rogues broadcast a commercial on television encouraging everyone to meet at the Hydro Sky Harbor for the greatest cruise of their lives. There, trillions board the Rogues' ginormous vessel, abandoning Nolan and his 96 best friends on the island.

With that, the Rogues' massive flying ship sets sail to their final destination: The secret arctic headquarters city where final plans will be made to shut HydroWorld down. Having everybody in one place will give the Rogues an opportunity to secretly escape HydroWorld on their flagship spacecraft, right before the black hole swallows the entire multiverse in their wake.

Regis is crowned king of the ship, giving him the power to brainwash every passenger on board. With luxurious amenities, delicious food, and spectacular scenery, this feels like a vacation for the passengers. What they don't realize is that they will never return home afterwards if the Hydro Rescue Team doesn't stop them in time. The Hydro Rescue Team gets to work putting together a plan to destroy the ship and stop the Rogues.

Several hours later, the Hydro Rescue Team docks with the Rogues' vessel aboard a Hydrohovership Helicarrier escort shuttle. They board the ship and sneak into the main command bridge to land the vessel, only to be spotted by Killer Croc, who immediately triggers the alarm.

The Hydro Rescue team is captured and handcuffed by the Rogues before being taken to King Regis, who tells them all about his kingship and the Rogues' plans to end HydroWorld for good. When Nolan's friend Jyoti asks him why, Regis answers with a big and loud song about why he takes authority over every other passenger and prisoner on board.

After the song, Regis traps the Hydro Rescue Team in a secret dungeon below his throne room. The kids try to escape it with no luck. Then Nolan suggests that they drill their way out using a new power driller vehicle he built using the spare LEGO pieces he found in the corner of the dungeon.

The sound of the driller's LEGO Powered UP motor triggers the audio sensors out in the corridors, alerting King Regis to unleash his guards on the Hydro Rescue Team for attempting to escape. Meanwhile, the kids make it out successfully and sneak into the command bridge of the ship. Nolan grabs the wheel and pulls the throttle to full speed, causing the ship's massive propellers to rotate in the opposite direction. The vessel turns in the opposite direction, back south towards HydroRidge Island, just as the guards finally track down the Hydro Rescue Team.

King Regis busts into the Command Bridge, attempting to swat Nolan out of the way. Then Nolan tells his friend Tasnia, who's closer to the wheel, to take the reigns instead when the guards pin him down. Tasnia fights with Regis over control of the ship, before she pulls the vessel into a wide turn, causing it to lurch sideways through the air as it travels. King Regis slips down the sloping floor and into a control panel, accidentally engaging the lever that activates the ship's hyperdrive.

The hyperdrive blasts the ship into full speed, blasting through the sky and arriving in HydroRidge airspace within seconds. Everyone cheers and thanks Regis for helping, even though he never meant to.

Tasnia lands the entire vessel on one of the giant launchpads at Potomac Shores Point, telling all the passengers to return home over the intercom system. Regis is arrested by the police for his foul acts of sabotage.

As the police escort Regis to the transport shuttle, Nolan tells him that there are better ways to be king other than sabotaging people to ride along with his sinister plans. He also tells him that the Hydro Rescue Team would never let him end HydroWorld no matter what he did to try and stop them.
