What bumosaur is that? - Andy Griffiths

Packed with full-colour illustrations and diagrams and extremely informative entries. Never again need you look like a fool when somebody asks you, 'What bumosaur is that?'

Features useful facts such as:

Bum-headed idiotasaurus - consisting of one large bum with a smaller bum-head atop, idiotic in both looks and behaviour.

Poopigator - just like an alligator, except browner. And smellier.

Also includes important - and frequently sought after - information about the greatest bumosaur battles ever!
