Let's start with MULTIPLAYER!!!

They should have quick race so 당신 can just pick one track an then pick another person, kart, drift and track.

New Mode: Survival Mode!!!
I'll explain this...
Pick any of the tracks 당신 unlocked.
Something based on the track will be chasing the 2-4 players down.

Last time I said Ghost Valley 1 should be in it. So if 당신 pick it, a big boo will chase you. Every lap they get a little faster. 당신 can set the speed at the beginning, 1-15.

Toads Factory
Chaser: A giant tractor

DK Summit and Rosalina's Ice World
Chaser: A giant snowball

Desert Tracks: Chaser:...
