Mystery House Marathon
Mystery House Marathon, or World Crown-Mystery Box, is the final Mystery House of Super Mario 3D World and its Nintendo Switch port Super Mario 3D World + Bowser's Fury, with thirty challenges lasting 10 seconds each for a total of 300 seconds, or five minutes. It is the Mystery House with the most Green Stars, and the only one with Boom Boom and a Stamp. Some of the challenges in this level are harder versions of the Mystery Box levels from previous courses and previous Mystery Houses.
