Hodge loves Chuggington Quiz Night – so when quizmaster Harrison loses his voice, Hodge volunteers to take his place. But he has a really busy workday with Eddie and doesn’t get any time to think up his questions. To try to save time, Hodge overloads himself and breaks his axle. Because Hodge is one of a kind, they won’t be able to find a replacement in time for him to host the quiz.
