The Bulborb is a fictional species of creatures found in the Pikmin series of video games. There is several different types of Bulborbs; the most common being the Red Bulborb (previously known as the Spotty Bulborb). The Bulborbs all share the same role in the Pikmin; and that is to attempt to eat and kill the Pikmin. Although a single Bulborb can usually easily overcome one or two Pikmin, the Bulborbs' main weakness lies in the fact they do not usually cooperate with one another, and thus, any single one of the Bulborbs can almost always be defeated by a large group of the much smaller Pikmin.
Bulborbs tend to sleep during the daytime, and thus are vulnerable to surprise attacks by the Pikmin. At night, the Bulborbs tend to gain considerable energy and are therefore generally invulnerable. This forces the Pikmin to have to hide during night, usually within the Pikmin storage facility known as an Onion.
There are two different types of Bulborb; those being the Grub-Dog family and the Breadbug family. The Grub-Dog family is both more robust and larger, while the Breadbug family is usually much smaller and only manages to escape falling prey to the Grub-Dog family members by mimicking the appearance of an average Grub-Dog Bulborb.
