Carson is a creative boy guppy with a vivid, offbeat imagination. He loves putting on costumes, telling stories, and speaking in silly voices. Carson doesn't just keep his imagination to himself either - instead, he uses it to invent exciting outdoor adventure stories for his friends to act out. He's great at bringing his friends together for some swim-sational imaginative play, both in the classroom and on the playground. His favorite article of clothing is a baseball cap, and his favorite lunch is a turkey sandwich with cran-apple juice.
