Analysis
Motos is a circular, robot-like enemy. It has 2 claw-like hands and 2 metal feet. It also has a small head on top of it's body. In the files of the game, it contains animations of what appears to be it throwing something (presumably an object of sorts) and of what looks to be it's idle animation.

It's actual behavior when placed in game is unknown, as it does nothing other than stand. However, in certain personalized copies of the game, player's have claimed that Motos were presumably in their copy. According to certain players, Motos were found in the courses Bob-omb Battlefield, Lethal Lava Land, Dire, Dire Docks, Wet-Dry World and Tick Tock Clock. It has been described to sit in place nearby a few small crates (the same one Mario is able to pick up and throw) until Mario comes near, in which it will allegedly begin throwing the boxes at them as a projectile. The Motos were said to have a finite amount of crates, and once they ran out of them, they would be helpless as they ran away from Mario, however, if Mario were to despawn and then respawn the Motos, the crates next to it would've respawned as well. It was said to be only be defeated by quickly grabbing the crates it throws and tossing it back at them, in which they would've explode and leave behind 3 coins.
