Finn

Finn - a fishbowl, knows a ton about sea creatures and the ocean, uses his knowledge of the ocean to give facts and make a lot of puns, wears an orange lifejacket and stripped white and orange pants, has a fish like tail, has fins on the sides of his head, when he's running it's shown water falls out of his head (that could mean that the water inside him is not vital to his survival he also feels like he's a big part of why they have so many wet floor signs), has a purple stripped wind-up fish named Barnaby Wilikers in his head, missing one of his teeth on the left side (upper set of teeth), extroverted, energetic, tries to get other Toons to laugh at his fish puns, somewhat forgetful, etc You - anything
