Who is my play-mate?

Who will play: at least four children above 2 years
What do you need: cards or draw by your self pictures with animals (two cards for each animal), a hat
How to play: Children should know which animal what sound makes.
Any child draws a card of the hat. After all children have a card they start to scream like the animal on it. They must found the other child who screams like the same animal. Much more children much more fun in this game.
