You need to find a secret girl in level 3 of Hailey. After that play rainy level of Annie's game and follow the rope to the end to find a hideout. Talk to that girl and load up frost peak level. She should be at the start asking you to find goblin hideout. You will find a way to get there on the left of an exhaust that leads to a small hole. But first interact with the lever to open the door or you will not fall into the ground. After you get to that secret place use teleport in front of the door so Moon will move there. Now teleport back and you will see her in an orgy with goblins. Shoot the board to change positions. It can be done every 30 seconds.
