Bum trilogy

The Bum Trilogy consists of three books by Australian author Andy Griffiths: The Day My Bum Went Psycho (2003),[1] Zombie Bums from Uranus (2004),[2] and Bumageddon: The Final Pongflict (2005).The books are aimed at children aged around ten and contain much toilet humor.

Because the word bum has an alternate meaning in the United States, the book titles were changes to use butt instead.

The third book is further renamed to Butt Wars: The Final Conflict.
