In Billy's Submarine Adventure, Billy's mum tells him that she is taking him on a unique adventure. Although a little apprehensive at first, he soon warms to the idea and his wacky adventure begins. As Billy journeys down to the seabed, he spots an octopus wearing spotted pyjamas reading a big red book and a sea horse playing football. With such unusual sights to behold, it soon becomes clear that not all is as it seems... Inspired by Julia Donaldson's The Gruffalo, Billy's Submarine Adventure follows on from the first book in Wendy's mini series, Billy's New Camera, Billy is just a little bit older in this second adventure. Written in rhyme and accompanied by colourful illustrations, the book will encourage young readers aged 2-6 years to join in and read along as they accompany Billy on his exciting journey.
