World 1-Tower

Start by hitting the large block above for a Leaf if needed.

Make your way upward along the ledges, collecting coins. Touch empty coin outlines to reveal them.

You cannot kill Dry Bones, but you can jump on them to stun them temporarily.

Continue upward until you reach the red ring. Jump through it and quickly collect the eight red coins that appear to get a 1-Up.

Get to the small ledge on the left side and wall jump above to reach Star Coin # 1.

Grab the checkpoint (a marker indicating progress) just above.

Enter the door a little further along.

In that room, hit the block for a bonus amount of coins, then exit via the other door.

SECRET EXIT: Instead of exiting the room normally, watch the green blocks moving around the perimeter. Wait for the blocks to leave an opening in the right wall, then jump through the opening to find a hidden passage.

Go through the pipe and continue to the secret flagpole. This secret exit opens the path to the Green Toad House and the Cannon, which will lead to World Mushroom.

Back in the main area, look above for more green platforms moving back and forth.

In the upper-left wall, you will see a red pipe. When the platforms emerge from the wall directly below it, jump onto them and enter the pipe.

Hit the P switch to make blue coins appear, but disregard them.

Wall jump via the vertical green platforms to reach the upper level.

Quickly jump on the brick ledges to reach Star Coin #2 at the top, then exit via the pipe.

After exiting the pipe, jump up the next couple of ledges and avoid the skeletal Piranha Plants.

To the left, you will see an alcove where Star Coin #3 sits.

If you are Raccoon Mario, wait for the green blocks to retract to the sides, then flick your tail to defeat the enemy and grab the star coin safely.

Continue upward to find more green blocks moving in the center. Wall jump from the sides to get onto them.

Ride the platforms upward and jump onto the final ledge above.

Enter the boss door to face Reznor.

There are four rotating platforms, two with Reznors. Hit the block directly below a Reznor, or flick your tail from the side to kill it.

Once both Reznors are gone, you have cleared the stage.
