Book is in French Dive into three new stories that will both frighten and delight you! Narwhal loves Halloween - it's a great excuse to dress up as a ghost, a mermaid, a banana or maybe even Maurice, the mustachioed moose. It's monstrously fun! Gelato, for his part, doesn't dress up: this time of year scares him, and he prefers to hole up in a hiding place until Halloween is over. But a scary sea monster appears and swallows Narwhal (greedily!)! Can Gelato, with the help of some great friends, find the courage to save his best friend?
