Stan Chin is a lazy sea urchin and proud of it. He uses his smarts to do as little work as possible. Although he doesn’t move much, he’s prickly and is always ready with a verbal (or physical) jab if someone gets on his nerves.

Finn is a young, mischievous flying fish with a punk rock edge. He loves playing pranks, ignoring rules, and listening to really loud music. Even when he bites off more than he can chew, Finnie’s impish good humor (almost) always saves the day.

Kiki is a cheerful, happy-go-lucky pufferfish. Small but mighty, she is a speedy little fish who can instantly puff to more than double her usual size. Kiki is super loyal and even braver for her friends than she is for herself.

Brains is a super smart brain coral. Wide-eyed with awe and excitement, he wants to learn as much as he can – about everything! Right now! Brains is very, very attached to his hat, which he calls his “thinking cap.”
