Goliath

Biography
Goliath was the main antagonist in Episode 14. His full name is Goliath Humpherdink Ankleberg Prince Dingleleisuer the Third (HOW ARE SOME OF THESE WORDS SPELLED!!?!?!?!?), but he goes by "Billy". Goliath is the strongest vegetable in the clan of Philistines, and he ultimately won a fight against Dave (Junior). He has a very high pitched, flamboyant voice that makes him sound way less threatening than the others believe. Apparently his friendly attitude towards his fellow friends is enough to make others weep.

Behind the Scenes
Goliath is voice by Billy Willie, who also voices George. The voice he did was inspired by comedian Ed Wynn, and 'Muppets Tonight' character Mr. Poodlepants.
