INSTANT NEW YORK TIMES BESTSELLER Grumpy Monkey and his jungle friends are trick-or-treating on Halloween amid strange noises and mysterious smells. Along the way, they are reminded that nothing can be scarier than returning home with no treats. On the spookiest night of the year, Jim Panzee and his jungle friends brave the dark to collect treats. Not only does the jungle look different at night, it sounds different. What´s that knock-knock-knock and that HAHA HAHA HAHA? And the smell? PEE-YEW! "Don´t be scared," they tell Jim. But then two glowing eyes flash overhead, and looking for treats is almost abandoned. Halloween in the jungle can be even scarier than trick-or-treating in your own neighborhood.
