Super Mario 64 on N64 - The Third Bowser World - Bowser in the Sky

The third Bowser world is located at the very top of the keep.

1. The easiest way is to push the crate back to the start so you can jump and take the first red coin.
2. You can't really miss the second one, which is on your path. Be careful all the same, as a plant guards it.
3. The third is a little further on, on an extension of the big platform below. You'll probably need to turn the camera around to see it.

4. This coin is on the path at the top of the "Lego" bend. To avoid any risk, stand at the edge facing the void and do a backward somersault.
5. The fifth is probably the trickiest, but with a well-calibrated somersault from the "log", you should get it without trouble.
6. No worries with this coin apart from a slight risk of electrocution. It's on your way, at the 2 rotating platforms.

7. You can't miss this one either; it's at the top of the pole, on your way.
8. The last coin is well hidden, under the staircase leading to the pipe at the end of the level. Don't forget it.

The star appears right behind the pipe.

After taking the star, jump into the pipe to find yourself face to face with Bowser, who is waiting for you. As always, you just need to grab his tail to swing him around and throw him toward the bombs around the platform.

Bowser is defeated and vanishes with a final groan, leaving a star behind. Take it and Mario will fly off on his own toward the end of the game.
