Continuity mistake: The Janitor takes one can of "Punch" out of a box in his Camaro's trunk. After the Camaro is towed, the Janitor removes a sack from the Camaro's passenger front seat, which now contains the cans of Punch. He was not shown moving the cans and there's no explanation of where the sack came from. Also, when the Janitor is carrying the sack into Willy's, it doesn't look like it contains more than a couple or few cans yet it supposedly contains many more. (00:03:55 - 00:09:40)
Suggested correction: He filled the sack with punch cans to use to kill the last animatronic character before he left, they didn't appear out of nowhere.
