Bobba are large worm-like creatures found on Fribbulus Xax, though there are rumours the the Bloogs have recently captured some to act as guards in their orbiting fortress. Being exceedingly muscular, Bobba hold their worm-like body upright even hopping along on the lower portion of it, which acts as a foot. They are indestructable and shoot huge, fast moving fireballs. Their eyes, though well adapted for low light, cannot see well during the day (they have no pupils) and thus they can only take short hops, often "walking" back and forth across a piece of land unable to see a way around or over any obstacles they encounter.
They only appear in Keen 6, Hard difficulty level, and only in a few specific levels (such as the Bloogbase Management District and the Bean-with-Bacon Megarocket), never more than one Bobba per level. Their rarity in comparison to babobbas implies that few bobbas survive to adulthood, although it is not known what threatens them in their youth.
