What is birthday hat hockey? ...
Take one birthday hat, remove the elastic thingie that goes under your chin.

Place hat on floor. Thwak it with your hand. With luck, the birthday critter will thwak it back. Volley it a couple times. Eventually, here, the birthday critter will take the hat and claim it as his/her own; volley it into the pantry or whatever. When you can't take it (either the game or the hat...) declare the birthday critter the winner and present a treat.

Rules may vary to suit your terrain...
