Kid's party games: The doughnut chomp. This also works for apples instead of the typical bobbing for apples (which I think is gross). New set of apples/doughnuts for each group and the kid can have their doughnut/apple when done.
Glow in the dark egg hunt. Could spray paint the eggs with glow in the dark paint instead of using glow sticks. Also, doesn't have to be for Easter. Could be a fun night time scavenger hunt or other fun summer game.
