In this hilarious follow-up to Unicorns Are the Worst! and Dragons Are the Worst!, Gilbert the Goblin's next adventure takes him to the frozen tundra where he's determined to find the legendary yeti. Gilbert the Goblin is the first to admit that he was, ahem, mistaken-unicorns actually throw the best tea parties, and dragons make delicious ice cream soup. This time, though, he can absolutely confirm that YETIS ARE THE WORST! Sure, they may seem cool and mysterious, but once you meet one, he's CERTAIN they're not all they're cracked up to be! And that's what Gilbert plans to do: meet a yeti. That is, if he can find one...but how hard can that be?

Mo Willems meets Bob Shea in this uproariously funny picture book about Gilbert the Goblin from the creator of Unicorns Are the Worst!. Gilbert the Goblin is absolutely, definitely, one-hundred-percent certain that dragons are the worst. They burn down everything in sight and they hoard all the gold. They melt every ice cream cone within a mile radius, and everyone is afraid of them. But really, it's the dragons who should be afraid of Gilbert and his tremendous goblin power! ...right?

Gilbert the Goblin infiltrates Santa’s workshop to prove that goblins are better workers than elves in the side-splitting latest installment in The Worst! picture book series, where even the strangest of creatures can become the best of friends. Everyone knows that elves have a reputation of being the hardest workers around—especially when it comes to the holiday season—but as far as Gilbert the Goblin is concerned that’s nothing but ho-ho-hogwash. A goblin’s to-do list is just as long as any elf’s; they just don’t feel the need to sing songs about it. To prove he can outperform any reindeer-watching, wrapper-paper-wielding, toy-tinkering elf, Gilbert puts on his merriest disguise to infiltrate Santa’s workshop. But can one lone goblin do the work of a whole team of elves?
