The Supersonic Fart by Helen Rose and Garry Parsons

It’s the birthday party of the year, and the guests are about to be totally blown away. But not how they might expect ...
 
Everyone has arrived for Jake's party: Grandma, Grandad, even Jake's cute puppy, Luna. Mum's made the most marvellous cake and the festivities are in full swing. But then someone does a stinker of a fart and everything starts to go wrong. Can disaster be averted?
 
With a hilarious fart chart at the end, this is a laugh-out-loud book to enjoy again and again.
