I witnessed this inter-dimensional flying hair monster summon itself from the nether world whilst at my girlfriend's apartment. I have the feeling these beasts are going to start showing up everywhere. Sick. On the bright side, I don't think it has teeth, just lots and lots of hair.
The good news is that it seems to have fallen comfortably onto her pillow, where I assume it will remain. Either that, or it'll excrete some sort of unearthly dark matter. One way or another, I'm not going to be the one cleaning it up.
