Alien Tiger Cow
Form a circle, standing. On the count of three, everyone will become an alien, a tiger or a cow:
" ALIEN: hold your index fingers up next to your head like antennas and say
"Bleep Bleep", bending inwards into the circle
" COW: bend forward, holding your right hand on your tummy and go
" TIGER: push your right hand forward, imitating a claw, and ROAR
Every player decides to become one of the three individually. The idea is for everyone to become the same, which obviously won't be the case the first time. Re-do this until everyone is in sync.
*Invent your own animals (or things) and let players become juke boxes, birds, whatever.
