King Pong is the bravest, strongest gorilla in the jungle but there's just one problem...he is a little bit smelly and he is afraid of water! Written by Clare Helen Welsh, this educational Early Reader book is book band Gold (aimed at 6-7 years, Year 2-3). The colour grading system is recognised by the Institute of Education which reflects the reading difficulty. The book content, language style, phonics and layout are taken into account to determine this.
