Super Mario 64 (et DS) : Third world of Bowser : Bowser in the Sky

Bowser's third world is at the very top of the dungeon.

1. The easiest way is to push the crate towards the start in order to jump to take the first red coin.     
2. You can not really miss the second one on the way. Be careful though because a plant protects it.     
3. The third is a little further on an appendix to the big platform below. It will surely return the camera to see it.

4. This piece is on the way to the top of the turn in "lego". To avoid taking risks, get on the edge looking towards the void and make a somersault backwards     
5. The fifth is probably the most technical but with a somersault well calibrated from the "log", you should have it without a hitch.     
6. No worries for this room apart from a slight risk of electrocution. She is on your way at the 2 rotating platforms.

7. You can not miss it either, it is at the top of the mast, on your way.     
8. The last room is well hidden, under the stairs leading to the end-of-level pipe. Do not forget it.

The star appears just behind the pipe.

After taking the star, jump in the pipe to find yourself facing Bowser waiting for you. As always, it is enough to chop the tail to make it spin and throw to the bombs around the platform.

Bowser is defeated and disappears in a last rattle leaving behind a star. Take it and Mario will fly alone to the end of the game.
