Tiny Tim Cratchit is the youngest frog son of Bob Cratchit and Emily Cratchit in The Muppet Christmas Carol.
Tiny Tim was born a cripple, and must carry a crutch when walking, and also has difficulty breathing. For all of his ailments, Tiny Tim remains cheerful, optimistic, and loving, and enjoys long walks on his father's shoulder. Tiny Tim's plight plays a major role in the eventual reformation of Ebenezer Scrooge.
