Nightmare Fuel / Home Alone 3

• Even though Alex managed to defeat the spies, which was awesome considering he is a kid, he still was lucky he survived because these bad guys were not humorous crooks like Harry and Marv. They were wanted by the FBI, and were armed with silencers and weapons. Beaupre in particular ends up being savvy enough to turn the tables on Alex toward the end, and if Beaupre hadn't accidentally picked up a toy gun instead of his real one earlier, that would have been the end of him.
• The lawnmower trap. Granted, you find out that it only gave Jernigan a funny bad haircut, but the lawnmower dropping into him and his screams make it look like something straight from a horror film.
• How Alice left Mrs. Hess to die: Tied up to a chair in front of an open door, leaving her to die of exposure to the cold weather. A pretty brutal way to die in a kids' movie.
