Grumpy Monkey Poop!

Everyone's favorite New York Times bestselling Grumpy Monkey is back in an original board book and ... he really has to go! Will he find the perfect place to poop, and when he does, will he still have to go?

Jim Panzee and his friends are having a picnic with lots of yummy things to eat, when Jim realizes he needs to go. But he's nowhere near home - and home is the only place he likes to go when nature calls.

Norman finds a tree Jim can go behind, but Jim disagrees: Too dirty! Porcupine shows Jim some rocks Jim can go behind, but Jim disagrees: Too smelly! Finally Jim finds the perfect spot but then ... he can't go. Nothing a little walk and fig can't fix. But now the perfect spot is taken!

Will Jim be able to hold it again until he finds the right spot at the right time? Or will Jim learn that sometimes trying to control both your body and your surroundings only leads to trouble...?
