A wide game for Beavers (and parents too!)
A large supply of "magic buttons" - empty milk cartons etc will be fine; a large field to play in!
Half of the group are treasure hunters, who have just found magic buttons in the forest. They have to get their treasure to their campsite on the other side of the field, but may only carry one at a time, without being caught by the trolls. If the trolls tag a treasure hunter by touching them, they have to give up their magic buttons to the trolls and go back to get another one. Once all of the magic buttons have either been successfully taken to the campsite or by the trolls, count them up to see who has the most. The trolls can then become the treasure hunters and start again.
