B.O.B (voiced by Seth Rogen) is a blue one-eyed indestructible gelatinous mass that was spontaneously created in a laboratory when scientists injected a chemically-altered ranch dressing into a genetically-altered tomato. He has the ability to absorb anything, can form into any shape, doesn't have a brain and digests objects within seconds (depending on size). He can also extend his body and detach his eyeball. He was captured in 1958 and was sent to Area Fifty-Something.
