Book excerpt: NEW YORK TIMES BESTSELLER • Jim Panzee, our favorite grumpy monkey, is feeling like quite the Scrooge this holiday season! It's Christmas time in the jungle, and Jim just can't get into the holiday spirit. Then Jim eats a "festive" green banana that makes him feel sick. Now everything seems worse. While all the other animals in the jungle are ready and eagerly awaiting Christmas, Jim can't stop feeling that this time of year stinks. But with his good friend Norman's help, Jim discovers that focusing on the good things around him instead of his own problems, is a reason to celebrate.
