This is a fantastic idea and I’m sure we will be stealing this one!
We had a problem in the fairy land on our daughter’s fourth birthday party: somebody stole all the lollies!
Lucky that somebody had left jigsaw pieces around, and when they were put together (a joint effort, this mum actually struggled with dad’s drawing…), there was a map that showed the way to the treasure a.k.a. the stolen lollies. Great for getting everyone playing together!
