An annorexic boy/girl who can be picked up by the wind due to their extreme light-weight proportions. It is known that some oliverchens have lost weight to such a magnitude, that they could pass through solid objects such as walls and even other people! Although this is merely a legend, there could quite possibly be someone capable of such an extraordinary feat. Oliverchens are sometimes mistakened as ghosts or apparations due to their ability to walk through walls.
Boy A: "Oh my god! That boy just walked through that wall!"
Boy B: "This place must be haunted or something!"
Boy A: "No, I think it was an oliverchen!"
