Wartihog makes an appearance in School of Dragons along with Speedifist and Clueless. Unlike his appearance in the book, Wartihog appears older and lacks the pimples on his face. During one of the quest, the player is required to speak to Wartihog and retrieve notes from him for the Headmaster. Wartihog can be found standing outside the Great Hall near the Headmaster.
