Tinkerbell Tag Party Game: This Tinkerbell party game should definitely be played outside! Each player is given a pouch of fairy dust. The player who is IT will tag the other players, who must freeze when they are tagged! The only way to be un-frozen is for another player to sprinkle them with fairy dust! For a fun extra have the pouches re-filled and ready to go home as a party favor. You can even have your very own special fairy dust recipe for the guests to make for the pouches!
