In a musical competition between cartoon features of Bugs at war with an opera singer, Sylvester buffeted by tidal waves in his gastronomic quest for Tweety, and two mice conspiring to induce house cat insanity, Daffy plays the drums.

Daffy disguises himself as Bugs to host the television show, but a sheepdog, on a day free from his work, walks into the studio, hoping to catch the bunny-rabbit (Bugs) that he saw on television on the previous week.

Daffy wants to be host. So, he banishes all others from the stage, including Pepe, Elmer, and Bugs. Still, the cartoons proceed on schedule, with Bugs in Scotland, Porky and Sylvester in a spooky, mouse-infested house.
