Markiplier spends nine hours trying to get the ending, which requires him to answer all the questions wrong and make Baldi chase him faster. He finally succeeds and enters Baldi's office, where he hears a distorted message from Baldi telling him to destroy the game and not tell anyone about it. Markiplier is disappointed by the ending and says he hates himself for wasting so much time.
