Crackers
Timer (or just count)
This one is best for individuals, possible choking hazard here so be careful who is playing (see alternate section).
Anywhere
For this one, everyone stands or sits in a circle (or around a table) with a plate of crackers in the middle. Starting with a random player the game master will say their name out loud, they have 5 seconds from the time they hear their name to say an animal, put a crackr in their mouth, say another person's name. The person they name then has 5 seconds to do the three things. If you take longer than 5 minutes, you are eliminated; if you say an animal that has already been said, you are eliminated. Play until there is one person left.
Scoring is, as always, completely arbitrary, you can award only the last one standing or award points on a sliding scale from based on elimination. Decide how you wish based on the number of players.
I use crackers because it gets really hard, especially if you are being picked on and your name is constantly being called (you can institute a rule about not saying the same person's name twice to combat this). You can use any food you like.
If you are concerned about choking, especially if playing with younger players, then you can have them stack crackers (or anything) on their heads and they lose if they fall. You could do something else for this step that maybe takes dexterity or concentration, you'll come up with something.
