Mini Mayhem

Mini Mayhem is the first floor in Mario vs. Donkey Kong: Minis March Again!.

Being the first floor, all the levels are relatively simple and easy, allowing the player to adjust to the game mechanics. The only enemy to appear on this floor is a single, solitary Circus Kong, not posing any possible threat (Circus Kongs only cause harm if they toss a mini into something dangerous). The plus rooms are slightly harder than the normal floor, with each level being significantly bigger, and there is also the addition of Mini Spear Guys and Mini Snifits.

The backdrop depicts a blue sky and green hills all painted onto a metal wall, with fake clouds hung from ropes scrolling across the roof. For the plus world, the only difference is the orange-colored sky. To win the player must safely lead the Minis to the door.
