For my daughter's second birthday I created a Hungry Caterpillar cake in the shape of the number two. The eyes were made from yellow and green gummy candy (I used jelly fish because they were flat) and the mouth is one raisin. Antennae were toothpicks with blueberries. To make the cake, I did a simple sheet cake, cut in half and stacked to make a layer cake, and then cut around and removed the pieces to make a 2. Any number would do!
