In some ways, children are harder to scare than adults. If you don't believe us, go back and watch some of the movies you loved as a little kid. You'll be surprised to find that, at random spots, they've inserted scenes that are bizarre, hallucinogenic and/or just plain sphincter-bustingly scary.
Willy Wonka and the Chocolate Factory: The Boat Ride
It's the uplifting story of Charlie, a down on his luck kid living with his impoverished grandparents who obtains a rare golden ticket allowing him a tour of Willy Wonka's awesome and wondrous candy factory in a premise that even Michael Jackson would describe as "a little creepy."
Right off the bat the kids see Wonka's delicious candy room, where everything is edible and thus completely awesome. After an unfortunate mishap wherein a fat kid drowns in a river of chocolate (it's how he would've wanted to go, really), Wonka invites the remaining survivors to hop aboard his boat, where he informs them that they're "going to love this."
