B.O.B. (short for Benzoate Ostylezene Bicarbonate) is one of the deuteragonists in the DreamWorks' Monsters vs. Aliens franchise. He 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. He is voiced by Seth Rogen.
