Wing Mario Over the Rainbow

Winged Mario Over the Rainbow is one of three secret levels in Super Mario 64, where Mario uses the Wing Cap to collect eight Red Coins. The entrance is on the left side of the third floor near Tick-Tock Clock. The level contains two platforms with a cannon on each, and four solid clouds. Two of the clouds are transparent and Mario can fly strait through them. The other two are not solid enough to walk on.

There are five wing cap ! Block's strategically placed around the level so that running out shouldn't be a problem.

The recommended sequence for collecting the red coins goes like this:

The center cloud has the first red coin, the cloud closest to it has the second. The third is on a cloud near a platform. Next, go to the platform, collect the fourth coin, and talk to the Bob-omb Buddy to activate the cannon. Aim at the sun, towards the other platform. Use that cannon to fire to the cloud with the green poles on it's underside. The two coin on top make six, the seventh is in a transparent cloud. Fly into it, then to the green poles, where the last coin hides. The star will appear back at the center cloud.
