When you collect all the star coins in World 7, you will unlock World 9, Level 7. Take the platforms under the overhang or let Bowser clear a path above them.If you die or do not complete the level, you will lose credit for the star coins you have collected. Don't touch the waves at all, or you'll instantly be fried. Take the platforms to the right as Bowser continues his assault. This makes the next stretch less of a headache. Be sure to hit the ? Block here for a Propeller Suit. Eventually you'll come to a platform leading down. You can hit the ? blocks for powerups, and it's very advantageous to at least be Super ("big") Mario for the area to come. Try to get Bowser to shoot horizontally in the same position to clear a direct path forward. If you though Bowser looked a bit smaller in person, you may want to think again. Hit it to end the first round of the fight. You'll really need to time this dash well to get to the switch. Normally you'd want to jump when he lands to avoid his shock, but in this battle this should be your cue to run straight under him to the P-Switch on the opposite side. When you see him crouch a bit he's preparing to jump high in the air and pound the ground. One of Bowser's moves allows you to do just this. If you have a Fire Flower, you can dodge these attacks and constantly pelt him. Occasionally he'll spit a clump of fireballs which can be carefully hopped through so long as you retreat and let them spread out. He'll mainly perform tiny jumps, or stand still and emit single fireballs you can easily hop. The King of the Koopas is easier if you have a fire flower, so grab one from the invisible block to the right of his door and try to make it to the battle with it. You can reach it with a careful wall-jump and some easy jumps. When Giant Bowser pursues you through the palace, this coin appears above three moving platforms. You won't get this coin until your battle with Bowser is well underway. You can wall-jump into it and back to safety, or use the small platform above it to sink right into it. The second coin appears in the area in which you move down a long shaft on dropping platforms. Leap to safety in the nick of time and land on the platform to the right. Take the platform down to it and begin running as soon as you touch the coin. Near the end of the first stretch of the castle you'll spot this coin floating near the lava below.
