Coins
At the start keep going forward down the "runway". The coin is on the submarine.
Take the first right after the start line to find the coin.
- Go along the track until the road splits into an upper road and a lower road. The lower one has the coin.
- After you get the third coin continue until you reach a wide open area. Turn left.
- Near the start/finish line is a 20 ring door. The coin is behind it.
Emeralds
Just after the loop is a door. Go through it and the Emerald will appear just behind it. (Red)
Turn left at the speed-up panel and go through the 50 ring door. The Emerald will appear on the yellow submarine. (Gray)
