From the author of Warning: Do Not Open This Book comes a lively story about a teacher’s special jar where her students keep their story ideas—but watch out when those ideas go on the loose!

The idea jar is where students keep their ideas—anything from a Viking to a space robot to a giant dragon. These ideas can be combined to make new exciting stories. But watch out when the ideas escape the jar—they might get a little rowdy! Adam Lehrhaupt’s newest picture book is sure to inspire creativity, imagination, and adventure.
