While playing around on SM64, I noticed something peculiar. There's a pair of goombas in Bowser in the Sky that, when loaded, causes three objects to load. The first and second of these objects are the two goombas, but the third one seems to be another goomba that's not detectable in any other way. This mystery goomba seems to have all the properties of a regular goomba, though I cannot figure out where it's located, or if it even exists the way a normal goomba does. Things get creepily philosophical by the end of the video...
Currently, our best hypothesis for the goomba's whereabouts (proposed by Patashu) is that its spawns off of the platform, placing it directly on the floor below it (i.e. the death barrier). If this were true, it would be impossible to interact with it, as explained in this diagram: http://imgur.com/XOPe98x.
Edit: It turns out our hypothesis was true! New video explaining it: https://www.youtube.com/watch?v=rEBMaAoKRvw
