Bumble

Known as the naughtiest chaos creator in the galaxy the Bumble was a giant furry creature with a giant mane of hair and a stripy stomach like a bumble-bee from whence it might have got its name. Fully grown the Bumble had the strength to knock buildings down with a single blow, crush buses with a stomp and knock a TARDIS down the street. One was witnessed in London 2064 but was captured and taken away so that it could cause no more harm or damage after running amok in the city.

The Bumble caused havoc and chaos wherever it was found and its moulting hairs had the effect of inducing laughter among those around them (the Doctor was immune to the effect). (DWA: Bumble of Destruction)
