The Rooftop is a bonus floor in Mario vs. Donkey Kong: Minis March Again!. On the level select screen, it is placed after Floor 4, Jungle Rumble. It contains twelve levels; the first six are unlocked by beating the main game on Normal Mode, while the remaining six are unlocked by beating the game on Plus Mode.
Every three levels feature a different type of mini toy, which are, in order, Mini Toads, Mini Peaches, Mini Donkey Kongs and a mix of all types of minis in the game, including Mini Marios. Completing one of these three-level sets unlocks the option to change the minis in most levels of the game with the corresponding mini toy or toys. However, Rooftop levels will not be affected by this change. These levels also feature a dominant mechanic as well as a different soundtrack depending on the mini that appears in them.
Several arches can be seen in the background of Rooftop levels, followed by some plains with Peach's Castle visible further away.
