List of Luigi sightings in Super Mario 3D World

In a similar vein to New Super Luigi U, 8-bit sprites of Luigi are hidden in most courses of Super Mario 3D World. Note that the 8-bit Luigis that can be found in the levels of World Mushroom and World Flower are in the same locations as their counterparts in the other worlds of the game; as such, only Luigis unique to those levels are listed.

In the Bowser's Fury campaign of Super Mario 3D World + Bowser's Fury, 8-bit Luigis may also occasionally pop out of the ? Blocks found throughout Lake Lapcat.
