Bubble Bass is a massive green bass fish. His first appearance and major role is in the episode "Pickles," in which he is angry that SpongeBob forgot to put pickles on his Krabby Patty. Since then, Bubble Bass has mostly had a smaller role in subsequent episodes. One of Bubble Bass's larger roles is in a Season 11 episode bearing his name, "Moving Bubble Bass," where SpongeBob and Patrick try and help him move out of his mother's basement.
Bubble Bass is overweight and wears an orange shirt, brown pants, and a pair of glasses. The front of his body is a lighter shade than his back. His chest has visible hairs, something which is not visible in his Kamp Koral design because he is a younger age.
