Sabrina, Aunt Zelda, Aunt Hilda, and Chloe form this pop/rock group for a talent show. When they lose, they use their magic powers to become big stars.
They sing "What's Your Favorite Flavor?" which is later parodied in the show by Weird Al Yankovic (voicing himself) as "I've Got an Electric Shaver."
The band's name is a parody of the Spice Girls.
