when mint asks about what the 3 little pigs story means either choose the first or second option, do not pick the third one. the next thing you need to do is when you need to hide the body do not go near mint's room, go in magnolias room and click on the bed to hide it there. continue as normal and youll get the second ending. p.s. the password for the door at the very end is 313, hope this helps
