I'm think I've beaten T.T. on every single course....
....
Except Whale Bay.
Which is the ONLY pure-hovercraft stage in the game.
Add to it, T.T.'s stats are terrible, and is the only real prize you get for beating said trials :/
Oh, and I just remembered....
On my N64 that I got a while ago, I have a copy of this game for it(Not motivated to playthrough all of it again)
The advantage with that, is easier multi-player :3
