Calavera Bulborb

The Calavera Bulborb is a boss appearing in Pikmin 4 (Salem version). It is a colorful and macabre bulborb that must be defeated in order to access the Green Onion and subsequently Green Pikmin.

The Calavera Bulborb itself is a bulborb that has white skin, a purple rump with skull-shaped spots, eyes with black sclerae and cyan pupils, and a pair of light blue teeth. It has a facial coloration resembling a Calavera skull, after which the creature is named. On its head is a tall, black top hat. The Calavera Bulborb is positioned in the center of a wooden coffin that is partially filled with dirt. Growing from this coffin are thick, thorny tendrils the Calavera Bulborb uses to grab, skewer, vacuum, or poison Pikmin.

The interior of its coffin is poisonous. To defend itself, the Calavera Bulborb jumps into a well. It randomly chooses one of four attacks, where it can either impale, grab, vacuum and eat, or poison Pikmin. Upon defeat, the Calavera Bulborb's tendrils shrivel up and die, and its coffin closes up. The beast also drops the Green Onion after its defeat, allowing Green Pikmin to be discovered.
