Ford Pines wrote in Journal 1 about attempting to locate the Crawlspace for years, but failed.
In the present, after Mr. What's-His-Face steals Mabel's face and flees, Dipper and Pacifica give chase. As they follow the monster. Mr. What's-His-Face is able to access the door by teleporting into the market, but Dipper and Pacifica are stopped when the door leads to a brick wall. Dipper then uses the President's Key to reopen the doorway to the Crawlspace. Dipper concludes that this is where Gravity Falls' weirdness hides during the day. They quickly find out that they are the first humans to enter the market alive, and they tried to hide their identities while they search for Mr. What's-His-Face. After Dipper accidentally blows their cover, they are put up for auction by the other monsters, with Mr. What's-His-Face winning the bid and taking them to the place where he keeps his stolen face collection.
