World 3-5

Grab one of the Propeller Blocks at Point 1 and use it to reach the P Switch on the mushroom pad on the right. Hit the P Switch to reveal several blue coins, then propel yourself upward to collect them.

Keep up with the spinning square at the center of the level, however. If you fall behind, you’ll die.

As you pass by all the Venus Fire Traps at Point 3, stay on the middle of the spinning square as you ride it up and jump up to avoid the fireballs the plants spit out. You may have to swerve left and right slightly, but you’ll make it through alright as long as you don’t veer too far off course.

Go through the pipe at Point 4 to enter the flag area and finish the level the first time. This will allow you to reach the ! Switch on the main map. Then return to finish the secret section of the level detailed in Point 5 and beyond.

After hitting the ! Switch on the World 3 overview map, return to this point and fly up to the red pipe. Land on the red blocks near the pipe and go through it to reach the secret section of World 3-5.
