Sometimes all you need is your imagination...It's a rainy day, and Anna and Kiki are stuck indoors, wondering what to play next. Suddenly, Kiki has an idea for a new game. "All you have to do, " she explains, "is think up a Think-Up and it will appear!" And she thinks up ... BUNNIES! Then they conjure up the most marvellous, magnificent MOOSE! And octopi! And nine HUNGRY koalas! Hmm ... is it possible to UN-think a Think-Up? With half-cut pages that make for funny surprises at every turn, this is a fresh celebration of imaginary play for the youngest of children.
