How about one of those inflatable bouncy-room things, a.k.a the Skull-knocker, a.k.a the Tooth-Loosener, a.k.a Lip-Splitter? Only if I could get the Totanic, which is an inflatable bouncy-thingie designed to look like the Titanic ramming an iceberg. Yes, such a thing exists. Do an Internet search if you don't believe me. The Totanic: It's an inflatable ship that's half sunk, with an inflated iceberg. As one rental site puts it:
Experience the thrill of sliding down the deck of the Totanic from 20 feet above the ground, with an icy cold bounce waiting for you at the bottom! This item is great for school carnivals and church festivals.
I won't ask if these people are out of their minds; I'll answer for them, and in the affirmative. I don't know of any other children's party activity whose inspiration is a maritime disaster. But why not? The Lusitotica: Nothing happens for hours and hours -- then there's a mysterious explosion, and the party's over in 17 minutes. The Edmund Totzgerald: If you have bad weather on party day, this is the Doomed Inflatable Bouncy Ride for you. If you're lucky, Gordon Lightfoot will compose a song about the event that's longer than the event itself.
