 After all the end credits finish the music continues as we see a door to  the giant freezer where Marla and Joe ran in to get away from Jack and Sam  and Anne forgot to rescue them. As soon as the song fades out Marla and  Joe call for Sams and Annes help to open the door to get out of the  freezer. There is a momoent of silence as they are both  end up frozen to death inside the freezer.
