"Dive into new stories that are sure to fright and delight! Narwhal loves Halloween--it's a great excuse to dress up in a spooky and silly costume, like a ghost, a mermaid, a banana, or maybe even Marlow the Mustachioed Moose. It's a skeleTON of fun! Jelly isn't dressing up, though--he's a little scared of this time of year, and would prefer to hunker down in a hidey-hole until Halloween is over. But when a scary sea monster makes an appearance and swallows Narwhal (gulp!), can Jelly, with the help of some super friends, pluck up the courage to save his best bud?"-- Provided by publisher.
