Mystery House

Mystery Houses are a series of courses that appear in Super Mario 3D World and Super Mario 3D World + Bowser's Fury. They involve completing a marathon of Mystery Box challenges to collect Green Stars. In these courses, the player is under a ten-second time limit to complete an objective, such as defeating every enemy or reaching the Green Star. These courses become available as soon as the player enters the world they are in, but Enemy Battles or the general map layout could make them inaccessible. They are available on every even-numbered world, including World Bowser, World Mushroom, and World Crown.

With the objective being to defeat all enemies to advance for both Mystery Houses, the levels Mystery House Melee and Mystery House Brawl may be references to Super Smash Bros. Melee and Super Smash Bros. Brawl, respectively.
