Catwoman plans to steal the voices of visiting British rock singers Chad & Jeremy by using her new Voice-Eraser on a morning talk show host. She later uses her fiendish invention on Commissioner Gordon, but not before he tells her where the British rock duo will be staying in Gotham City, which turns out to be stately Wayne Manor.
In order to gain access inside the manor, Catwoman arranges to give Dick Grayson a free dance lesson & disguises herself as Miss Klutz, a teacher from Duncan's Dance Studio. After sneezing from a nearby dogwood plant, she gasses everyone and retreats.
Later, Batman and Robin pay a visit to The Dance Studio. There they make quick work of Catwoman's cronies; Eenie, Meanie, Miney and Moe and attempt to apprehend The Felonious Femme Fatale. She subdues them both with a knockout drug and transfers them to a giant echo chamber, where a dripping faucet magnified 10,000,000 times, threatens to reduce their brains to mush!
