"Johnny Boo lets Squiggle borrow his magic hammer so Squiggle can work on a mysterious project, but that leaves Johnny Boo with nothing to do today. He has lots of great ideas about how to spend his time while he waits, but ends up getting bored of each and every one of them. Not to worry, though. Joined by Squiggle, the Ice Cream Monster, and a big new friend, Johnny Boo will still have a hilarious adventure...and maybe even learn something about sharing"--Provided by publisher.
