Rainbow Ride is the last main course of Super Mario 64 DS.
Location: Upper floor of castle. On the right side in a hole in the wall as you face course 14.
Description: A sky level with rainbows, magic carpets, and a flying boat.
Bob-omb Buddy: Go below the red coins (see star 4), and wall jump above the blue coin box all the way to the top. The bob-omb buddy is there.
ShortCut!!! When you start, turn around and long jump to the pole behind you. This way, you skip one hard part of the course Just For Fun: Go to the Bob-omb Buddy's right, and long jump straight out. You will land far, far below on another platform.
Original stars
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 ride another carpet. Ride that to the end of the line also. There will be two carpets. Take the one to the right. 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.
Star 3: Coins Amassed in a maze
Get all 8 red coins. Go straight from the four spinning platforms and wall jump and backflip for all the red coins.
Star 4: Swingin' in the breeze
Go left from the four spinning platforms and climb down the first pole. Go past the shy-guy (the flying one) but ignore the second pole (be careful as this is a see-saw platform) and go to Mario's right (our left) and carry on going that way, you'll be able to see what to do. Then you'll reach a wooden slope. Make your way up and swing across to the star.
Star 5: Tricky Triangles!
Go left at the four spinning platforms and and go past the wood slope. Hit the flat ! switch to turn the triangles upsidedown. Do a triple jump on the first two to skip two of the triangles. The star is at the top.
Star 6: Somewhere Over The Rainbow
Get to the floating ship (see star 1) and shoot out of the cannon through the rainbow ring. The star is on that island.
Star 7: 100 Coins
Be sure to get all the blue coins where the Bobomb buddy is. Also get the red coins. Don't even bother going up towards star 1 and 2. Go towards star 4 and 5 for the rest of the coins.
