Replying to Teaching Park ski culture

So I convinced this kid who I babysit to start park skiing this winter. He's nine years old and currently races. He said he's super stoked on doing tricks. Last time I babysat him I talked to his parents about getting him into it and they are wealthy so they didn't mind. I offered to drive him home on some nights that we are both there to make it easier for their parents. Anyway, he talks about doing daffy and twisters and stuff like that. He has a tramp so I'm trying to show him some spins an grabs and stuff. I showed him some park skis to show him the difference from race skis and he was judging them on graphics and if his bindings would match his skis. (Luckily I found a cheap pair of Armadas that he likes and showed his parents). How do I teach him about park skiing culture and what park skiing is like compared to racing and how he views it? He's pretty much a gaper and I'm trying to bring him into the sport correctly. Of course IM not forcing him into anything, Im trying to guide him, and I'm not sure how to do that.
