Peacock Bass is a regular character in the game, Swimmy Sea, that was released on Version 1.0.
Peacock Bass looks like a green fish with a huge square mouth. It has a blue, green, and yellow fin at the end of his body, and two orange fins on his sides. He has two small white eyes, and black crosses all over his body. His body also changes color from the top to the bottom, from dark green, to green, to yellow, to finally orange.
- Although he has a similar name as the Bass, he does not take the anatomy of a musical instrument like him.
