Bob's Omnitrix symbol is located on his chest/stomach region.
Powers and Abilities
Bob's sticky skin allows him to stick to flat surfaces.
Bob is very slow, as displayed in the commercial when attempting to save Gwen. He was practically unable to move.
Bob the Blob solely appears in a Cartoon Network Latin America Commercial promoting the Ben 10 marathon "Ben 10 Total Access". In the commercial, Gwen is hanging off of a large steel girder as a Xenocyte crawls up her leg. Ben attempts to save her by transforming into an alien, but accidentally turns into Bob the Blob, who is way too slow to rescue her. Eventually the Xenocyte latches onto Gwen's head, pulls herself up and immediately slaps Bob before walking off.
