Jim the chimpanzee is in a terrible mood for no good reason. His friends can't understand it--how can he be in a bad mood when it's SUCH a beautiful day? They encourage him not to hunch, to smile, and to do things that make THEM happy. But Jim can't take all the advice...and has a bit of a meltdown. Could it be that he just needs a day to feel grumpy?Suzanne and Max Lang's hilarious approach to this very important lesson is now in a toddler-friendly board book format! It is an excellent case study in the dangers of putting on a happy face and demonstrates to kids that they are allowed to feel their feelings (though they should be careful of hurting others in the process!).
