UR-2 is one of Grizzle's sidekicks. He is an intelligent, suave robot who wears a blue robot suit and black bow tie. He is often seen to give Grizzle tips, which annoys Grizzle. He can change his hand into a wrench and does not have regular feet, but just floats around. He has smoke that comes down whenever he moves. Sometimes, he gets confused about his name when Grizzle calls him, and he tells Grizzle that he "is not," which angers Grizzle and makes him have to explain to him that his name is UR-2, such as in A Little Help. He can be a little dumb and apprehensive at times. He often uses big words that the target audience of the show, ages 4-8, would not know the meaning of. Even though he is loyal to Grizzle, it can be proven that he does not really like him that much and is a bit afraid of him.
