Cerulean is a cyan seed-shaped enemy with oval-shaped eyes with dark blue pupils and orange fins behind it.
Like Pteran from previous games, Cerulean softly flies forward at a slight angle, turning around whenever it hits a wall. On rare occasions, Cerulean will loosely try to follow Kirby. This enemy poses little threat.
Cerulean's name is derived from the word cerulean, a blue-green color, referencing its color palette.
