What's there to do when you're stuck inside on a rainy day? If you're like Kiki, with a big imagination, you teach your sister how to play the Think-Ups. It's easy: you take turns thinking up any animal you like (A bunny! A moose! An octopus! A koala!) and, just like that, that creature (or several of them) will appear. In a blink, your house will be overflowing with hopping, hungry, messy Think-Ups. Quick, Kiki! What are the rules for ending the game? A charming story about keeping boredom at bay, with sure appeal for little animal lovers and creative thinker-uppers.
