PIG is a Hairy Snotter [PDF ebook] 

Pig finally gets to go on his surfing holiday with the school. (He got the holiday because he was in the Head Teacher’s Secret Toilet without asking.) While Pig is away, Suki tells him that he has lost his bedroom. Mum has got rid of all his stuff and from now on he will have to live under the stairs, just like Hairy Snotter. This must be Bob’s Revenge. What can Pig do? Boys love PIG! Peter Ian Green has another hilarious adventure in this book, one of the bestselling series ‘PIG’ by Barbara Catchpole. Coupled with fantastic black-and-white illustrations and an easy-to-read diary format, the laugh-out-loud humour and tale of friendship will appeal to all readers.
