Everyone's favorite New York Times bestselling Grumpy Monkey is back in board book edition of this hilarious bedtime story about dealing with a sibling and frustration when you don't get to do what you want!

Jim Panzee is going to a slumber party and there's LOTS to do. Jim plans on bobbing for mangoes, going termite fishing, and of course staying up all night!
     But Jim gets more than a little frustrated when his little brother, Tim, ruins his good time. All the things Jim wanted to do aren’t fun anymore. Then, one by one, everyone else falls asleep (even Norman!), while Jim is determined to stay up. How long will he last? And will Tim ruin this, too?
     In this board book, Jim deals with sibling rivalry and the aftermath of staying awake way past his bedtime.
