In this colorful preschool game, players use a bouncy wormy die roller to feed leaf tokens to bizarrely unique caterpillars in an effort to turn them all into fantastical butterflies. There are three levels of play, starting with cooperative shape and color identification all the way to competitive, memory-based play.
The goal of the game is to transform all of your caterpillar cards into beautiful butterflies by feeding them leaf tokens. In general, players will take turns pushing down the wormy roller to spin the die inside its body. Depending on the level of play, that information will tell you which leaf tokens to find from the leaf pile. You must then find which caterpillar wants to eat that leaf, feed it to them, and then flip them over to their butterfly side and "fly" the butterfly away. When all the caterpillars have been transformed, you win!
