You make a fun kids movie, full of wacky lighthearted antics and enough goofy aspects to keep the kids entertained. But then it happens - the furnace in Home Alone, the toilet in Look Who's Talking Too, etc. - something TERRIFYING shows up and that's all the kids remember for years and years.

What kids movie scared the crap out of you? Keep in mind the boat scene from Willy Wonka and the Chocolate Factory is just assumed.
