Woody first appeared on TV in Knock Knock along with Andy Panda and Papa Panda. He continually pesters the two pandas just for the heck of it before eventually being taken away to the looney bin. Woody became widely popular after that and went on to do more shorts. Soon after his own arch nemesis was brought on, Wally Walrus. Woody has also made enemies with Buzz Buzzard, pestered little Chilly Willy, and again had adventures with Andy Panda.
Woody is the uncle of Splinter and Knothead.
