Can't say that I blame you for blocking out all memory of her streaming avatar. That being said, and having checked, it turns out that the toilet/animorphs thing was Aurelia, though. Marigold is the one who streams BDSM dungeon porn games with a 'really-1000-years-old-honest-to-dog' avatar.
Also the time she surprised Marigold with the solid gold sex futon/fart fetish stream ending. I'm not sure if that actually indicates a deviant, or instead just that she is pretending to be one, which is arguably scarier.
