Finn is an energetic and extroverted Toon. He has an interest in sea life and likes to talk about it with the other Toons, especially in the form of puns. He sometimes can go overboard on it and continue on making puns, even if a Toon doesn't like it, based on his interaction with  Glisten. He also can be somewhat forgetful, such as forgetting to not get too close to  Vee, based on their interaction with each other.
