First appearance of the Tasmanian Devil.
While Robert McKimson and his team were discussing new adversaries for Bugs Bunny, animator Sid Marcus suggested offhandedly that they have used everything except a Tasmanian devil. They looked the animal up in the encyclopedia and decided he would make a good foil for Bugs.
Aside from beginning one question he asks to Bugs with "what for you", Taz mostly speaks proper English in this cartoon, instead of the "caveman-speak" he's more popularly known for and would adopt in later appearances.
Producer Edward Selzer disliked the Tasmanian Devil and asked that no further cartoons be made with him. It was studio head Jack L. Warner who asked for more cartoons with "Taz Boy" (as the animators called him), on the strength of audience response to the character. Hence, there is a three year difference between this cartoon and Taz's next appearance in Bedevilled Rabbit (1957).
The music heard over the title cards is an original composition by Milt Franklyn. It would later be re-used as the title card for Tweet Zoo (1957).
