James Kochalka's beloved all-ages series continues with another goofy romp! When Johnny Boo announces a play date with his quiet new friend Rocky the Rock, trusty sidekick Squiggle is left to find a new friend of his own. How about this nice fellow named the Mean Little Boy? He sure is fond of his butterfly net, and he's got a great game to play with Squiggle... But wait a minute, maybe the Mean Little Boy isn't actually so nice! It's up to Johnny Boo and Squiggle to find a way out of this pickle. The fourth Johnny Boo book is packed with laughs and charm, with just the gentlest touch of potty humor.
