The heroes are approached by a kid, who begs them to battle with his Remoraid. Ash accepts, but Brock warns him he'll need the strength for the Whirl Cup. Misty asks the kid why does he need to battle and learns the kid wants to evolve his Remoraid into an Octillery. He shows them that the battles will be fought on a dry land rather than water. Misty goes to battle the kid, since she wants to train her Corsola. The kid sends Remoraid and Misty Corsola. Remoraid starts with Water Gun, but gets reflected by Mirror Coat.

Marcellus shows them he has many Remoraid, who were caught from many locations, from which his evolved into an Octillery. However, they have a hard time evolving, so Marcellus shows them why. He sends Octillery and puts it in the tank. However, the Remoraid avoid it, as if they are afraid of it. Brock thinks the Remoraid are not aware it evolved. Remoraid use Water Gun on Octillery, pushing it away, so Octillery puts itself in a jar. The heroes feel sorry for it. Marcellus claims that Octillery was saddened that it couldn't fight in the Cup. Misty has an idea for Octillery to make a new friend. For that, she presents Ash, the Pokémon imitator.

Meowth thinks they can capture Remoraid and be paid by the visitors of their Water Park to fish the Remoraid. Team Rocket suck the Remoraid through the hose, while Octillery observes. As the heroes have dinner, Misty and Brock heard something. Marcellus goes to see the Remoraid and encounters Team Rocket. Octillery hides under their van, while James sends Weezing to use Smokescreen. After the distraction, Team Rocket escape in the van, but the heroes notice a trail of water puddles.
As they arrive to the docks, Meowth uses the crane to board the Remoraid tank to the ship. However, an Octillery wraps him. Jessie and James get it off, but gets tackled. The Remoraid watch as Octillery bashes the tank to set them free. With a final bash, the Remoraid are freed into the sea.
