Slice an apple into 6 to 8 pieces, removing the core and seeds.
Have children use a toothpick to pin together two apple slices to form the wings of a bug. Place a head on the top by inserting a second tooth-pick halfway into one of the slices, and putting a grape onto the other half.
Once they've mastered this critter, kids will naturally discover all kinds of others to create. The more fruits you have, the more they'll use and eat!
