Chuckers, a blue dolphin in glasses, getting bonked on the head by a game controller

Meet Chuckers

Chuckers is a Pacific white-sided dolphin from the waters off Alaska who followed a ship south and took a wrong turn straight into our studio. He's sweet, he means well, and he has zero impulse control. If a sign says "Don't press," he's already pressed it.

If anything in the game ever breaks, you already know who to blame.

It's always Chuckers.
