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 have lots of suggestions for how to make him feel better. 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?
