King Arthur ( Graham Chapman) and his knights are led to the cave by Tim the Enchanter ( John Cleese) and find that they must face its guardian beast. This is guarded by a monster whose nature is initially unknown. The Cave of Caerbannog is the home of the Legendary Black Beast of Arrrghhh. The iconic status of this scene was important in establishing the viability of the musical. The rabbit is the antagonist in a major set piece battle, and makes a similar appearance in Spamalot, a musical inspired by the movie.


The scene in Holy Grail was written by Graham Chapman and John Cleese. The Killer Rabbit of Caerbannog is a fictional character in the Monty Python film Monty Python and the Holy Grail.
