Tox Box

Tox Boxes are enemies in Super Mario 64 similarly to Thwomps that only appear in Shifting Sand Land. They are large red boxes with different faces on each side, except for one side lacking a part allowing the player to walk into the Tox Box, revealing the enemy to be hollow. They deal damage by crushing the player, and roam set paths where they are located.

Test Map
In Super Mario 64 DS, a secondary test level exists full of Tox Boxes that have the unique behavior of roaming wherever they want, while all other Tox Boxes have hardcoded paths. The test map only has the Tox Boxes and a gray floor, and no other notable details. This test map is also notable for the fact that this is the only special test map except for the main test map with several general assets.
