Titch is little. Everything he has is little--his little pinwheel, his little tricycle.
Peter and Mary are big. Everthing they have is bigger than Titch's, and better.
Their bikes go faster. Their big kites fly higher. And their huge instruments are much louder. BANG! But then Titch gets a little seed, and what cones fron it is a hundred times bigger than anything Pete and Mary could ever have!
