It has an un-holy amount of breathing holes on it. (01:23:00 - 01:27:10)
Trivia: Director Danny Steinmann is more infamous for directing pornography. This is why there's more sex in this film than previously. He also didn't care much for directing the actors, so they often had to improvise their scenes.
Trivia: Originally, the film was supposed to pick up where the ending of the previous film left off. Tommy Jarvis is taken to the same hospital as Jason's body. While trying to get to the morgue, he murders seven people on the staff. When he arrives, he finds Jason's body rising from the table. The adult Tommy then wakes up in the van, on his was to Pinehurst.
