here's a rat with a bat and a very flat cat and a frog in a bog with a jet-rocket log, but the duck in the truck might just SUCK THEM ALL UP! Crash! Bang! Pow! Kersplack! This book will bring on a giggle attack! The Cat on the Mat is Flat by Andy Griffiths and Terry Denton is a collection of utterly nonsensical, totally irreverent rhymes. Dr Seuss meets Revolting Rhymes - perfect for reading aloud and learning to read.
