Many people have felt the wrath they have wrought, but not many people have actually seen an invisible weasel.
Invisible weasels are a type of weasels that have mutated over the years to have the ability to turn invisible. Unlike most weasels that people can see, the invisible ones have not been domesticated, and are fond of harassing humans.
The crimes that these weasels commit most often are stealing socks, so that the owners can never have matching pairs, and hiding car keys.
There are the occasional weasels that will even mimic alarm clock sounds, so as to wake people up before their actual alarm goes off.
If any of these things has even happened to you, then you may be the victim of an invisible weasel crime. Though they may sound like average weasels, just hidden from view, they are not.
Invisible weasels can be very dangerous if cornerd. If you think there is a weasel in your house do not confront it, instead call your local weasel authorities.
