Trivia
"Pacifica invites Dipper over to her mansion in order to get rid of a ghost, otherwise the Northwest reputation would be ruined. Even though she 'hates him and doesn't want to be in the same room with him for 2 minutes.'
 * A clip of the episode was previewed at the 2014 CTN Animation Expo. One of the attendees there was able to detail what occurred in the clip, claiming:

''Dipper is thinking he's all awesome and 'Yeah, I dealt with these ghosts in a convenience store once and anything Mabel told you about that is a dirty lie.'

''But then everything starts getting out of control, there are animal heads on the walls that start oozing blood, and Dipper says 'Well, it couldn't get any worse.'

''Then the ghost comes out of the fireplace (he’s like a big lumberjack sort of ghost, with fire for a beard and an ax) and they hide, Pacifica is trying to get Dipper to do his 'nerd thing' and get rid of it, but the only tip the Journal has is 'beg for mercy.' The ghost finds them and then the clip ends."
