Continuity: When Debbie is killed in the hammock, in all shots of her, the quilt covering the hammock net has patterns sown on it, such as flowers. However, in the closeup of Debbie as the knife comes through her chest, the quilt covering the hammock is the same one as before, however you can now see it is suddenly the other side of the quilt.

Continuity: When Chris knocks Jason out with the shovel, the position of unconscious Jason's legs changes between shots.

Plot hole: Jason somehow manages to get the two halves of Andy's dead body on the wooden ceiling rafter, with no blood dripping onto the hammock and staining it, or getting none onto the floor. Debbie then gets into the hammock, and about a minute later, blood starts dripping - for no apparent reason. Why?

Continuity: When Chris shows Debbie the hammock, between shots the way the net hangs and the position of the net changes.

Visible crew/equipment: In the scene where the snake leaps out the cage you can see a dodgy looking fake snake attached to a wire spring.

Visible crew/equipment: When the kids first arrive at the camp, as the camera pans as the van pulls up you can see a little bit of a white screen, a small bit of the camera and the top of a crewmember. It's clearer in the blue strip of the van.

Visible crew/equipment: After Vera says "uh-oh," as her and Shelley sit in the car outside the grocery store, the camera pans around to the side window. You can see a hooded cameraman reflected in the small triangular window, as the camera pans.

Visible crew/equipment: When Loco, Fox and Ali stand by the van before they steal the gas, the long black boom pole is clearly reflected in the back window of the van.

Continuity: Jason approaches Loco with a pitchfork with five prongs, but the pitchfork that enters Loco's stomach has only four prongs.

Continuity: At the end of Part 2 Jason was unmasked, showing long hair and heavy eyebrows. In Part 3 he's unmasked again, but he looks totally different. He has some hair but is mostly bald. His face looks horrible, as his eyes don't line up, his skin is grayish, etc. Part 3 was supposed to have happened the day after 2, and yet he is now bald and his features are even more distorted.
