Beanie brings Admiral Bubbles on a school trip to Aqua World, hoping his goldfish will learn proper behavior from the other fish. Instead, Admiral Bubbles is outraged at this public display of enslavement. Beanie doesn’t notice, he is too busy trying to impress Nia with his knowledge of fish. During the Killer Whale show, Beanie and his class get splashed by a big wave and Admiral Bubbles is “conveniently” swept away into the pool with the whales. Temporarily set free, Admiral Bubbles swims from aquarium display to aquarium display, searching for a way to plot revenge on the human jailers. Beanie ditches his touring class and goes “underwater” to catch his goldfish. Tracking down Admiral Bubbles, Beanie uncovers his goldfish’s plan of drowning Beanie’s class when they tour the brand-new but still unfilled, “Titanic Tank”. Admiral Bubbles manages to trap the students in the tank but Beanie is able to “pull the plug” on the scheming fish, but all the aquarium’s creatures escape into the ocean. Admiral Bubbles is quite happy with this result and Beanie is left wondering if he didn’t play right in the goldfish’s “fins”.
