Children can join in this Fimbles story with four sound effects - the hooter, Rockit's 'glung' sound, Ribble's squeak and Rockit making a 'brmm brmm' sound. Easy to understand symbols show which sound button to press on each spread. The story is based on the television episode, Hooter, when Florrie finds a hooter and the three Fimbles have fun making noise with it....
