The Warblettes are Pizza Time Theatre background vocal characters. They were three singing crows who would rock side to side. They would often announce and sing backup for the show.
There were two variations of the Warblettes. One variation was black, and the other was white with bright dresses and rainbow hair. The second variation is the rarest, with only a few known to exist.
The Warblettes were replaced for a short period of time in 1978 by The Mopsey Sisters, who were three singing mops. They were brought back the following year.
