You're gonna be bothered by how cool I am.

No, you're definitely not too sensitive! I seriously can't believe this was produced! What were the reactions of the people watching the kids play on it? Since you said you felt like the only one who was appalled, were they all smiling and seemingly having a good time?

I wonder what how the discussion went before any of the kids decided to try it.
Kid: Look Mom, a bouncy slide! I want to go down.
Mom: *sees that's it's obviously supposed to be the Titanic (despite the probable sign nearby)* Sure!
Kid: *Is too young and never saw the film or heard about the Titanic* But Mom, why does it look like a sinking ship?
Mom: *pffft* Oh, over a thousand people died when the real ship sank years ago. Go ahead! Pretend you're one of them. It'll be FUN! :D:D
Kid: ... Oookaaay.

Disgusting! I'd love to see the comment thread, if there is one, on their website!
