Johnny Boo, a friendly young ghost, and his ghost pet Squiggle combine their individual talents to prevent a monster from stealing Johnny's secret ice cream stash.

When Johnny Boo is busy with another friend, Squiggle tries to make a new friend of his own but instead gets captured by a butterfly-hunting boy.

"Johnny Boo zooms to the moon on a star-powered skateboard, where he meets a spunky little girl ghost named Susie Boom. She has BOOM power, which is pretty darn loud. Luckily, the moon has ice cream. But oh no! It also has an ice cream monster, just like back on Earth" --

Johnny Boo creates an incredible Ice Cream Computer that can turn anything into delicious ice cream. Old toys that you don't want to play with anymore? Ice cream! Clods of dirt and grass? Ice cream! It works great... until Squiggle decides to turn himself into ice cream! Then: Johnny Boo time travels to the future, where the Mean Little Boy tries to add him to his butterfly collection. Can Squiggle save the day, or will everyone get turned into ice...

"Are you scared of the dark? Did you know that when the clock strikes twelve, that's when the midnight monsters come out? Johnny Boo knows, but that won't stop him from skateboarding on the back of a wild Tiger and plucking pumpkin ice cream from the gaping maw of a Spooky Tree. He does it all to impress Susie Boom, the cute little girl ghost who lives on the moon. Hopefully she's watching everything with her telescope!"--Provided by publisher.

"James Kochalka's beloved Eisner-award-winning series takes a wintry turn as Johnny Boo and Squiggle discover the delights of eating snow -- and the importance of staying warm! Kids love to eat snow! It looks a lot like ice cream... hey, maybe it really IS ice cream! Johnny Boo and Squiggle are excited to find out, unless the Ice Cream Monster eats it all first. Armed with his gigantic and mighty Ice Cream Fork, he seems unstoppable...until all that...

"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 -- oh NO! -- 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...
