Pokémon Sun and Moon - Rotom can possess an entire f------ Pokemon Center building

So a Rotom can take control of an entire building as long as it has a functioning electrical grid… huh, im assuming though he is incapable of movement in this state just from size? Cause the idea of a Rotom making its own movable haunted mansion is pretty spooky, like Monster House pokemon edition.

If Rotom can become/possess an entire building like that does walking through the front doors qualify as vore or puking?
