Finn is a light blue fishbowl filled with water, wearing an orange life jacket and white trousers with orange stripes. A missing tooth gives his smile a playful edge, and as he moves, water sloshes from his head — though it doesn't seem to bother him one bit. He's often seen chatting animatedly, sharing fun facts about marine life alongside a stream of fish puns. Inside his bowl, a striped purple wind-up toy fish named Barnaby Wilikers bobs along, occasionally visible during his idle moments. Finn's boundless energy and extroverted nature make him the life of any room, though his enthusiasm can sometimes overwhelm quieter Toons. He's genuinely joyful and loves nothing more than making others laugh or marvel at the wonders of the ocean — even if his forgetfulness means he sometimes repeats the same joke twice.
