Peter is a creative boy guppy with a vivid, offbeat imagination. He loves putting on costumes, telling stories, and speaking in silly voices. He doesn't keep his imagination to himself: instead, he uses it to invent exciting outdoor adventure stories for his friends to act out. Peter's great at bringing his friends together for some swim-sational imaginative play, both in the classroom and on the playground. He loves to wear baseball caps and eat turkey sandwiches with cran-apple juice. His best friend is Kadian.
Peter has dark skin, violet hair, and green eyes. His tail is blue with yellow stripes.
