Tiny Tim is a cat with a broken leg that appears in A Special SESAME STREET Christmas. Maria finds the cat in the alley behind 123 SESAME STREET -- the injured cat had slipped on an icy fire escape. Maria dresses the cat up with a red ribbon, & puts a cast on its broken leg.
Maria introduces the cat to Leslie Uggams, & the pair decide to call it "Tiny Tim" in honor of the character Tiny Tim from A Christmas Carol.
They both show the cat to OSCAR THE GROUCH, who accuses it of breaking into his TRASH CAN on November 19th & stealing 2 fish.
At the end of the special, OSCAR has a change of heart & takes the kitten in, declaring "Are you people gonna stand around singing while that poor cat freezes? Hey, hand him up here."
