When Mabel finds a blank book in Dipper’s stuff, well, he can’t really expect her to NOT write in it, can he? Only, when she opens it up and starts her Mabelish ramblings, she finds Dipper actually stuck in the book, trapped by an extradimensional being demanding they give it colors. Which, okay, for Gravity Falls is basically Tuesday, but whatever. Naturally, Mabel and Dipper are going to be completely serious and compliant with this weirdo’s wishes. Oh, who am I kidding? When are the Pines twins ever serious or compliant?!

So, technically, this is a Gravity Falls coloring book. But it’s also basically a short graphic novel, so there’s that. The Pines twins’ character is all over this book, right from the sparkly pink ink and stickers festooning the cover. The back and forth dialogue between Mabel, Dipper, and the color-sucking monster (Chamelius Pendraggin, “pigmentologist”) is amusingly in-character and funny. The pictures get quite goofy, but they are also very funny–classic Mabel whimsy makes up a huge portion of it (and how could that be anything but awesome?) with some amusing Dipper asides and lots of commentary from Dipper on Mabel’s pictures. This is one of those books that, although it’s clearly intended for kids as a coloring book, it manages to be a fun read for fans of the show, even if they’re waaaay over the intended age bracket. Recommended. ( )
