The Wagoneer prominently displays a sun/moon roof during the mantis attack, but just a few minutes later when it is flipped over in the supermarket parking lot, it clearly does not have this accessory.

R.L. Stine's Jeep Grand Wagoneer's fog/driving lights turn on and off while the giant praying mantis is chasing it.

When Stine answers the door and talks to the police, the position of his right arm changes repeatedly.

Supposedly they are from New York, which requires a front license plate as well as a back one, but a front license plate is never seen on their car. New York Inspection & Registration stickers are also visible on the lower driver's side of the windshield.

Lorraine deliberately crashes her car into the werewolf, then has time to catch her breath and reassure everyone that she's OK before the airbag goes off.

When Zach first enters Stine's basement he is scared by a cuckoo. The cuckoo cuckoos four times but the hands on the clock show 2:00. In R.L. Stine's "The Cuckoo Clock of Doom," main character Michael Webster travels back in time and messes up the space-time continuum.

Lorraine must plod incredibly slowly while bringing the poodle a drink so she doesn't spill the water But when she does spill some water when she sees the dog levitate, she must tip the bowl a long way over since it was almost empty.
