Part 11

Hop down to the next floor and repeat until you see two stacked Firebars. Crouch to get under the higher one.

Jump onto the rotating gear. The first Star Coin is in the center. Wait for the Podoboo to start moving down after reaching its peak, then run and jump over the gap to grab it.

Hop onto the next rotating gear and jump over the Firebar.

Face the Dry Bones. Stomping and ground pounding will only temporarily break it apart; use a fireball to destroy it.

Hit the Large ? Block to get two coins and a Tanooki Leaf.

Jump onto the platform and let it be pushed up by the lava geyser, then hop off onto the chain platform.

Watch out for the large lava geyser near the beginning of the chain platform.

Continue to the row of three Podoboos and let them fall before passing through.

Be careful of the chain platform connecting the two stone platforms, as a lava geyser shoots up from there.

Grab the Checkpoint (an auto-save point you restart from on death) Flag.

Move right, hop over the Firebar, and grab the second Star Coin.

Further on, approach the first Thwomp. Let it 'thwomp', and as soon as there's enough room while it moves back, jump behind it to collect coins.

For the third Star Coin, do the same for the next Thwomp. As it moves back up, hurry behind it into the crevice. Jump at one side of the wall, and as you slide down, press 'A' to jump to the other wall. Continue this wall jump sequence until you get the Star Coin, then jump to the platform above the Thwomps.

Move left and grab the 1-Up.

Jump down onto the right Thwomp, let it slam into the ground, then jump off to the right.

Continue right past the Dry Bones.

Stay to the side as Bowser shoots fireballs down the center path. Run to the end and turn left, being careful of the Dry Bones.

After Bowser finishes his fireballs, he will jump closer to you over the lava on the wooden bridge. Keep moving forward to avoid his homing fireballs.

To get past Bowser, stay to the south edge and sprint past him before he shoots his first fireball.

Once past, run as fast as you can but stop early enough to avoid him jumping in front of you.

Once he has landed, run past before the first fireball is shot. He won't jump far enough back this time, so keep running to the end of the bridge.

Jump onto the big black button with the red Bowser head on it.

The bridge will fall, revealing Bowser as a Goomba with a Tanooki Leaf.

Hop through the castle door and hit the orange Warp Box to teleport to the roof.

Grab the Green Clock for extra coins.

Hop up the crates and take a running jump at the flag at the top.
