The other stuff that was talked about - the new "magic" - is situational within the game, and it's connected to the in-game quests. There are three "Driving" magic pins that give you access to "tracks". On the track, you and whomever else wander in are trying to grab trophies (one credit per trophy on exiting) and gas cans (extends your driving time). You exit when you leave or when you run out of gas.

Diving magic is similar, but you collect gems and there's no time limit. There's also spacesuit magic, but I don't think there's any point other than to go through the small "space walk" section and get to the area past it.

I recommend checking out the in-game maze in frontierland. Start at Big Thunder, see if you can get to the top of Tom Sawyer's Island. Coincidentally, this is also part of one of the quests...

Try vmkingdom.com - they (at least used to) have a pretty good walkthrough.

I did it once about three months ago - couldn't even begin to remember what happens where without being in game looking at it.
