A white, black and brown kitten with a brown patch over his nose and right eye. As his Broadway/video name suggests, he is always doing somersaults. In the original London production he was not present as an ordinary character, but Tumblebrutus was one of Growltiger's pirates, played by the same actor as the one who played Alonzo. Bill Bailey may have replaced on of the four nameless kittens listed in the Original London Cast recording. On Broadway he did the mating dance with Victoria.
