Lemmy Koopa's boss fight

This level begins with a blue Pendulum Platform with a ? Block containing a power-up above it. The player then uses more Pendulum Platforms to cross a pit of lava, with a Dry Bones on a platform in the middle. More Pendulum Platforms are found above the lava, followed by a Dry Bones on a row of Brick Blocks, one of which contains a power-up. A section of multiple Pendulum Platforms above the lava follows, with Lava Bubbles and a Dry Bones acting as obstacles. The Checkpoint Flag is found, followed by some platforms and Lava Bubbles. More Pendulum Platforms and a Red Ring follow. A Dry Bones is found on a stationary platform, and is followed by more Pendulum Platforms and Lava Bubbles. The boss door is found at the end of the area, which leads to the top of the castle. A Fire Flower in a Hidden Block can be found next to the boss door. The player must then use the red and black cannon at the top of the castle to shoot themselves into Lemmy Koopa's airship.

The boss of the course is Lemmy Koopa, who now uses bombs (with the same star pattern as his rubber ball) and tosses them at the player while periodically rolling around the arena. After getting hit two times, he starts throwing larger bombs that have a bigger blast radius. Lemmy’s bombs explode when they reach the wall unless the player touches them beforehand, which will light their fuse early.

Star Coins

	The first Star Coin is found between two Pendulum Platforms near the start of the level.
	The player needs to have either a Super Acorn or a Mini Mushroom for the second Star Coin, which is suspended in mid-air directly after the Checkpoint Flag. Peachette can also be used to reach this in New Super Mario Bros. U Deluxe.
	Near the end of a course, the third Star Coin is in a Warp Pipe almost submerged in lava.
