In The Muppet Christmas Carol, the members of the family include Bob Cratchit, wife Emily Cratchit, older son Peter Cratchit, twin daughters Betina and Belinda Cratchit, and youngest son Tiny Tim Cratchit. The offspring of the frog and pig couple follow common cartoon convention of the boys (Peter and Tim) being frogs, like their father, while the girls (Betina and Belinda) are pigs, like their mother.
