What do you get for the kid who destroys everything ?

Pickles is a great kid. He is funny, kind-hearted and just an all around great person. I hope he never changes.

But when it comes to toys... He is a one-kid wreaking crew.
He doesn't really own any toys, usually because once he touches them they mysteriously get damaged in some way.
I've tried remote controlled cars, electric guitars, board games, portable game systems (he had a Nintendo DS...once), an electric scooter, action figures... you name it I've bought it. The only thing he owns that hasn't been destroyed (yet) is his Playstation 2 and the games that go with it. I am amazed that it has lasted 4 years.
He's asked for some pretty pricey items for Christmas this year and as much as I'd LOVE to get them for him. I just can't see wasting all that money on things that won't last longer than a week or two.

I'd like to get him something that can hold his interest and won't end in up as a pile of rubble, but my mind is going completely blank. (any ideas ?)
I did buy some clothing for him and a bucket of K'Nex. He's also getting an MP3 player (he wants a Zune...I don't think so).

There must be something out there that is Pickles-proof....
