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?
