Alright I admit I was wrong about some things. I belive Old Man McGucket is the author and Gideon is "he". Stan is preparing Dipper and Mabel for the day the evil side of Gravity Falls is coming. He goes into the vending machine every night to count the days they have left for the day. Robbie is a zombie, look that up on Youtube.
