'''Lemmy's Swingback Castle''', or '''{{world|Acorn|castle}}''' is the [[castle]] level of [[Acorn Plains]] and the first Castle of ''[[New Super Mario Bros. U]]''. The course contains lava and [[Pendulum Platform]]s. It is the final course of the Flying Squirrel Pack in [[Boost Rush]]. It is unlocked by completion of [[Mushroom Heights]] or [[Rise of the Piranha Plants]], and its completion unlocks [[Layer-Cake Desert]] and its first level, [[Stone-Eye Zone]].

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 Block]]s, one of which contains a power-up. A section of multiple Pendulum Platforms above the lava follows, with [[Lava Bubble]]s 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 [[Cannon|red and black cannon]] at the top of the castle to shoot themselves into [[Lemmy|Lemmy Koopa]]'s [[airship]].

The boss of the course is Lemmy Koopa, who now uses bombs (with the same star pattern as his [[magical ball|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.

|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]]''.
