Squish Ball Cat is a Special Cat that could be unlocked by a particular Serial Code and evolve into Muscleman Cat at level 10. As the in-game description states, Muscleman Cat sees the truth inside and is Macho Cat's trainer. Everyone is fascinated by its rippling triceps. This cat character is a distant relative of the Titan Cat. You can have these game characters in our fanart The Battle Cats Squish Ball Cat and Muscleman Cat cursor pack.
