This level will revolve around having to wait for blocks to rise and fall in the lava, which while it is blue, is still as lethal as ever. Follow the stage as normally, axing the Bully if you want, until you reach some ?-Blocks, one of which will have a power-up in it. At this point, you will have to deal with some Parabones here, which are annoying enemies that will come back to life if they don’t drop in lava. When you reach the Green Star Ring, wait until the blocks are near you to touch it, otherwise you will have to wait and you might run out of time collecting the coins.
Collecting all eight coins will get you Green Star #1. The next section will have those blocks rising out of the lava, but it will be a long chain and you will need to avoid some spinning spiked rollers. Along the way, there will be a small, circular platform on the side, which has the Stamp and a little further ahead, there will be a Mystery Box. In the bonus room, you will have ten seconds to defeat a single Bully, so quickly roll into him a few times to knock it into the lava, earning you Green Star #2.
After returning to the main area, you will find the Checkpoint Flag just ahead, as well as left-to-right section. The blocks here will be going in and out of the wall now, so continue until you reach round platforms that have the spiked rollers rotating around them. On the second set, you will find Green Star #3 on a smaller piece jutting out of the second round platform. Not long after that will be a green pipe, taking you to the last section. Defeat the three Bullies on the tilting platform, which also causes some platforms to appear, leading to the Goal Pole.
