The big
red (or red-orange or
orange, depending on whom you ask),
hairy monster vaguely shaped like a misshapen
tooth from the
Warner Brothers animated shorts. His only features are eyes and he wears
tennis shoes. First introduced in 1946 in the
cartoon "Hair-Raising Hare" (where the
mad scientist refers to him as "Rudolph").
Bugs Bunny torments him while doing a
hairdresser schtick ("Such an IN-teresting monster!"). He only appeared in three of the original Warner Brothers' cartoons (there were some later TV appearences).
In his book, "Chuck Reducks," Chuck Jones discusses the origin of the name. There was a file of "irrelevant information" kept by the directors and animators. In it Jones found a note about a turtle named "Gossamer."
