"Ha llegado una de las celebraciones que más le gustan a Narval: ¡Halloween! Hay tantos disfraces posibles: de mazacornio, banagato ¡todos ellos narvalásticos! A Medu, en cambio, Halloween le aterra y prefiere esconderse a esperar que pase. Pero cuando un monstruo marino se zampa a Narval, ¿podrá Medu reunir a la superpandilla y armarse de valor para salvar a su mejor amigo? Otra nueva aventura de esta pareja acuática. Tan divertida y narvalástica como siempre, y con una nueva y determinante misión: ¡hacer que te lo pases de miedo!" -- Amazon.com

"In the hilarious eighth book of this blockbuster graphic novel series, Narwhal and Jelly celebrate the spookiest time of the year -- Halloween -- with a super twist! Dive into three 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
