Lemmy's Swingback Castle

Lemmy's Swingback Castle, or  is the Castle level of Acorn Plains. The course contains lava and rocking platforms suspended by chains. Lemmy Koopa is the boss of this course.

Layout
Most of the course is suspended over lava, and the player(s) must use the blue rocking platforms to navigate and maneuver over the lava. Later in the course, there is a sub-level that contains a Star Coin with a platform almost entirely covered in lava. At the end of the castle, there's a blue door which leads to the top of the castle. The player must then use the red and black cannon 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 bouncing balls) and tosses them at the player while periodically rolling around the arena. After getting hit two times, he'll start throwing larger bombs that have bigger blast radius.
