Super Mario 64 (et DS) : Second world of Bowser : Bowser in the Fire Sea

The second world of Bowser is at the bottom of the stairs leading to the basement, right after the locked door (key in the first world of bowser). It is necessary to pass the big starry door then to find the first star of level 9 (Abyssal Basin). It takes 30 stars to get through the door. To finish the level of Bowser, just follow the path. Falling into the holes will not be lethal but it will quickly lead Mario to the mainland when he burns his buttocks. This page will just tell you where to find the 8 red pieces showing the star right next to the pipe leading to Bowser.

1. After crossing met the first "ugly", take the path in grid to arrive at the first red room.     
2. Soon after the first ugly, on the platforms that lean when mario walks on.     
3. After being mounted along the green bar, in a corner of the cage

4. Under the elevator of the cage. Climb on and off before it starts. The room is just below, you have to jump into the void to catch it.     
5. Take the elevator and take the climb a little further on your right, the room is just above a ugly     
6. A little further in the "unfolding" climb

7. On the left in front of a flame lance enters the passage where the lava goes up and down.     
8. Just above the last pole that goes up and down over the lava.

From the last post, do the pear tree to find yourself at the top of the structure and get the star. You can also run (or walk) on the small wall.

After taking the star, turn around to enter the giant entonoir (beware of the bridge crumbling just before). Bowser clashes like the first. You have to try to go behind him in order to catch his tail (button B) then turn Mario and let Bowser go to a mine. The only additional Bowser attack is a big jump that will tip the platform when it falls. He can also teleport. Once defeated, Bowser will leave a key.
