This Book Is Seriously Silly! (a Narwhal and Jelly Picture Book #2) by Clanton, Ben

No smiling or laughing allowed. Don't even think about it. Jelly means business in this seriously silly interactive picture book follow-up to the bestselling This Book is Dangerous!, a spin-off of the beloved Narwhal and Jelly series.

Who messed with the title of this book? Was it YOU?

Hold in those smiles and giggles and don't you dare make a silly face or sound -- Jelly is a SERIOUS jellyfish, and this is a SERIOUS book.

Jelly has serious plans for this book and doesn't need any smiling, laughing, funny faces OR noises to derail it. And even if you do silly stuff Jelly will still be serious . . . even if he had a fuzzy pink mustache, or a name like "Jellysquish," or wore silly striped socks with silly faces that made silly sounds. Hey, don't let that give you any ideas!
