Murray the Hippo (also called "The Murray", although more by himself than anyone else.) is a fictional hippo featured in the Sly Cooper video game series for the Play Station 2. He has no known surname in any of the games, although he is often referred to as "Murray the Hippo" or "Murray Hippo" when full names are listed, a long going tradition in animation by having the characters' species be their last name. He is voiced by Chris Murphy throughout the games, although many note that Murphy's tone of voice when portraying the character changes with each game.
