Tumblebrutus Tumblebrutus is the alternative name for Bill Bailey. The name is a portmanteau of "Tumbler" and "Brute", making him an energetic, acrobatic character who's also rough and violent - very much a troublesome boy! Growltiger's Last Stand ... His bucko mate, GRUMBUSKIN, long since had disappeared, For to the Bell at Hampton he had gone to wet his beard; And his bosun, TUMBLEBRUTUS, he too had stol'n away - In the yard behind the Lion he was prowling for his prey.
