The Hole in the Middle

No wonder Morgan has always felt a little empty inside. He was born with a hole in the middle!  His best friend Yumi has lots of ideas for making Morgan whole, but nothing works. Then one day Yumi gets sick, and can't come out to play. Little by little, as Morgan bakes cake for Yumi and brings her flowers, the hole in his middle gets smaller... until it's nearly the same size as a belly button!
