Flip some cake and eat it too with the very Hungry Caterpillar! One sunny Sunday, the little caterpillar hatched out of a tiny egg. He was very hungry. Just like the hungry caterpillar, eat your way through fruit and snacks alike, before you can build your cocoon and become a butterfly. But, be careful what you eat, a stomachache will set you back! You'll never know when the food will mix and flip, filling your week with surprises!
