Harry is one of Stanley's pets and one of the two tritagonists of the Playhouse Disney TV series Stanley. He is an obese brown bulldog and associates with fellow pet Elsie, with whom he sings the theme for the Great Big Book of Everything in every episode. He often refers to the others as "dude" and sometimes acts slightly goofy, such as when he realizes how well he gets along with Elsie, her being a cat, he surprisingly states that he thought she was a Chihuahua.
