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 ladders 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 . . .
