Walkthrough: One in Moon Caverns, head up the path to come to a lava pit drop down to the platform below. You will find a number of winged Dry Bones after you do, and you can use Cappy to capture one to fly from the platform across the lava. As you do, what out for rising pillars coming out of the lava and Sherm Tanks shooting at you from the other side. Speaking of Sherm Tanks, ditch Dry Bones in favor of capturing one of them after reach the other side. After defeating all the foes in your way, pilot the Sherm Tank over the bridge until you reach the other side. Once you do, blast a hole in the nearby cage to get another Life-Up Heart.
After you do, leave the Sherm Tank in favor for another Dry Bones in order to fly to the next platform. Once there, again switch over to another Sherm Thank to blow open the cage guarding the Spark Pylon, and then use said Pylon to reach the area above. Once there, a panel will activate the moving platforms that head to some Hammer Bros. Capture one of the with Cappy as you approach, defeating the other and then breaking the walls ahead to reach the other side. Once you run out of walls, leave the Hammer Bros and get on the next platform.
There will be two Tropical Wigglers on this platform; dodge the first and capture the second. Spread out to collect the Coins you see, and then look for a platform on the right you can cling to. Wrap around the other side of the fence as the moving platform passes it, and then regain your original positioning. After doing so, stretch out to obtain the Purple Coins you see on your ride. At the end of it, ditch the Wiggler and dodge another to reach the next platform.
As you you proceed across the bridge towards a brick wall, you will have to face off with a Banzai Bill wearing a hat. Knock off the hat and then use Cappy to capture it, and then destroy the bricks as you head up and to the right. Try to pass the coin rings as you do, as well as defeating any Bullet Bills that cross your path. Break through the next wall where it looks weak, and then attack the next wave of Bullet Bills. As your meter start blinking, quickly crash in the Bullet Bill Launcher and then claim your next Banzai Bill. After capturing one, continue onward to the next platform.
Once there, leave Bill and head up to find a button and a Moe-Eye. Hit the button to create an invisible platform, and then capture the Moe-Eye to see and quickly cross the path. After you do, you will come to a Spark Pylon up to the top area. Here, you will with battle Chargin' Chuck. Easily knock of his helmet, and then use Cappy to capture him as well. Use his charging attack to get through the groves of boulders up ahead. After blasting through, leave him and then jump up to find a ledge full of boulders. Head to the left and capture another Chargin' Chuck, using his charge to break through the boulders and carefully get across the narrow path. Once there, head toward the next Spark Pylon. But after using it, a surprise fighter will look for some revenge.
