A cream-and-brown queen who appears to be close with Gus the Theatre Cat and also is part of the three-cat chorus for "The Old Gumbie Cat" and "Bustopher Jones". In the 1998 film she was played by Susan Jane Tanner, who had been the original London Jellylorum, and thus Jellylorum in the film is close to Jennyanydots' age. In some other productions, she is younger, more around Bombalurina and Demeter's age. She is possibly Gus/Asparagus' or Skimbleshanks' mate.
Jellylorum is portrayed by Susan Jane Tanner in the 1998 film, as well as in the original London production.
