simple game of tag
Choose a group of cubs who start out as zombies. This works best if you pick a little under a quarter of the students in the start. These cubs will be the zombies and they have the power to zombiefy the other players by tagging them. The only rule is that zombies are only allowed to walk without bending thier knees. The other cubs must run to avoid them. If caught by a Zombie they then become a zombie also. The game ends when everyone has been zombiefied.
