When Mr. Zinger’s hat flies in and interrupts Leo’s playing, the two of them construct a story as to how exactly the hat took off.
Three children, Tom, Hannah, and Shadowchild, who represents the reader, are made to guess, using the concept of binary logic, the color of the hats on their heads.
One fine day, from out of town–and without any warning at all–a magic hat appears in the sky. It tumbles and bounces through the air and makes magic wherever it lands. Everyone is delighted as, one by one, the townspeople are transformed into giant playful animals. And then a wizard arrives.
