Peanut Hunt
Before the party begins, go outside and hide a bunch of peanuts. Give each child a sand pail and tell them to act like elephants and go in search of their peanuts. The kid with the most peanuts wins a prize.
Hungry Lions
Choose one or two people to be the "lions." Let everyone scatter around as the "antelopes." The lions chase the antelopes. Those who are caught by a lion must freeze with their legs in a straddle position. They can be unfrozen when someone goes under their legs. The game can go on until everyone has been caught or the kids get tired.
Monkey See, Monkey Do
Play an animal version of Simon Says called "Monkey See, Monkey Do." Have one person act as the "monkey." They instruct everyone what to do. But the guests are only to do what the person says when they use the phrase "monkey see, monkey do" before the command.
Hanging Apple
Hang apples from trees and have guests try to eat the apple like a giraffe. Turn it into a competition by having everyone do it at the same time and see who can finish their apple first. Have them place their hands behind their backs so you're sure they only use their mouths.
