The Giraffe and the Pelly and Me - Roald Dahl

Billy's biggest wish is to turn a weird old wooden house into a wonderful sweet shop. But then he finds a giraffe, a pelly and a monkey living inside - they're the Ladderless Window-Cleaning Company! Who needs laddders when you've got a giraffe?
 
They become best friends and when they meet the richest man in all of England, there's a chance that Billy's scrumptious galumptious dream just might come true...
