Tattypoo is the white-haired Good Witch of the North in The Muppets' Wizard of Oz. As played by Miss Piggy, she is very fond of the Munchkins and likes to drop in for a cuddle or two. She also seems to be fond of penguins. Tattypoo and her sisters (the Wicked Witch of the East, the Wicked Witch of the West, and Glinda, the Good Witch of the South) once formed a popular singing group called the Four Little Pigs.
