Super Mario 64/Rainbow Ride

Rainbow Ride is the last main course of Super Mario 64 DS. To access it, go to the right of Tick Tock Clock and into the hole.

Star 1: Cruiser Crossing the Rainbow
From where you start, ride the magic carpet. Watch out for the flamethrower. If you stay off a carpet too long, it will disappear, so be careful of that as well. After reaching the end of the first rainbow, take a right and rid another carpet. Ride that to the end of the line also. There will be two carpets. Take the left one. Be careful not to get pushed off by the spinning platform. When you reach the end, get onto the pirate ship. Get the Wario cap (if you aren't Wario), then hit the ? block. Go back to the other side of the ship, and get the star.

Star 2: The Big House in the Sky
Follow the same path you took for the first star, but take the right carpet this time. Ride it up to the big house. Here, you can ride the carpet, or get the Mario cap and use the ? block to float up and get the star.
