Master Shake is one of the three main protagonists of Aqua Teen Hunger Force. Unlike Frylock who is an uptight super intelligent box of french fries and Meatwad who is known to be a dimwitted yet lovable ball of meat, Shake is a rude, selfish and lazy (In earlier episodes, he believed he was the leader) milkshake. Although he can do good things along with the other two.
As his name implies, Shake is a giant white drinking cup with a pink bendy straw protruding from his head. Although Master Shake does not have a nose, arms, or any reproductive organs, he does have two yellow hands with only four fingers connected to each side of him. His lack of arms is shown to make picking up objects somewhat difficult. While Shake doesn't have legs, he refers to his base as his "one thick ankle" in "Kangarilla and the Magic Tarantula." Just like Meatwad and Frylock, Shake occasionally wears clothing, but does not typically wear them.
