"Mine's big, yours green as leaves in spring. I can pull mine on a string . . ." So begins this charming story of two friends who embark on a flight of fancy, as they compare and contrast their imaginary friends in a classic children's game. The book's imagistic text invokes all sorts of exciting creatures and situations, from the mysterious being that eats chestnuts to the one that "lurks in nooks and crannies" to the "poor lonesome soul" who has vanished. With striking illustrations and a compulsively readable rhyming text, this surreal picture book is both a delightful read in itself and a perfect starting point for all sorts of discussions.
