Katie Honors is a really sweet kid. She has a smile for everyone, almost all the time. She can clean right up and say goodbye at a playdate when her mom says so. But sometimes Katie isn't ready to finish playing and doesn't feel sweet at all. When this happens, she becomes Stinkeroo! She slams the door shut and hides in the curtain. Her emotions feel uncontrollable until they EXPLODE... and Katie Honors is back to herself again. But her friend, James, assures Katie that sometimes he's Stinkeroo, too, and she is not alone in her feelings.

Rachel Vail and Hyewon Yum have teamed up once again for Sometimes I'm Stinkeroo to show that even the sweetest kids can have a tantrum with unexpected consequences and that it's always possible to make amends.
