Ceruleans are enemies in Kirby's Return to Dream Land. They are blue-green seed-shaped enemy. Ceruleans have similar shaped eyes and fins as well. Their pupils are blue in color while their seed-shaped fins are brown in color. Ceruleans' fins can come in multiple sizes, especially in Extra Mode. Ceruleans appear in many levels such as Cookie Country, Raisin Ruins, White Wafers and Nutty Noon. They attack by just flying around at a slight angle. Ceruleans will turn around and fly the opposite direction whenever they hit a wall or other obstacle. On rare occasions, Ceruleans will try to follow Kirby and his buddies (Meta Knight, King Dedede, Bandana Waddle Dee). Any hero who touches a Cerulean will take damage. Ceruleans can be defeated easily. If Kirby Inhales a Cerulean, however, he will not receive a Copy Ability for doing so. It is to note that Cerulean's name comes from the color "cerulean". Cerulean is a bright dark blue color, which is strange since Cerulean the enemy is blue-green in color.
