As his name suggests, Bubble is a large, round bubble with large, sharp, even teeth, and round black dots for eyes, constantly displaying a vacant expression. Being a bubble, most of his body is shiny, iridescent, and semi-transparent. When it is necessary, Bubble can form a long, reddish tongue that he shares with Caine. When his mouth is closed, his teeth are still faintly outlined. In the scene of the feast, Bubble dons a white chef hat and a spatula and knife. His pupils are capable of enlarging or falling off.
