When you can't go outside to play, it's time to call on your imagination—and summon all the marvelous creatures you can think up. 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.
