Felix's favorite toy, a robot dog, is lost in the land of the trolls.

With a little help from an all-seeing troll witch, Felix and Calcite get close to finding it. That's when they learn a big problem is standing in their way: Garganto, a giant who guards the path ahead. Garganto says no one gets through his gorge--even if Felix's toy is on the other side. But he's never met a duo like Felix and Calcite!

Artur Laperla, creator of the hit Super Potato series, presents a new set of laugh-out-loud adventures perfect for first-time readers of graphic novels. When Felix discovers a tunnel in his toy chest, he finds a land of trolls and a new best friend: Calcite! Felix learns that trolls are named after their favorite rocks, love munching on their favorite snacks (also rocks), and have really runny noses. Together, Felix and Calcite will encounter confused gnomes, cranky giants, talking frogs, and much more!
