Steve is a fictional commercial character used in the latest Peanut Butter Snickers commercial. Apparently, he ate some Peanut Butter Snickers before going swimming in the ocean. He was then eaten by a shark. The shark says that he tasted good because of the Peanut Butter Snickers. He was also said to have tasted better than a character known as Katrina because Katrina didn't eat any Peanut Butter Snickers while Steve did.
