So, for years, these things have been the creatures of my nightmares, and I'm sure some of you have seen them. I discovered a strange creature in my bathroom earlier, and I was googling it, and didn't come up with any results (it kind of looks like a thistle bur with a black worm poking its head out like a turtle shell, fucking terrifying), but I did find out that these things (see above) are called plaster bagworms.
Bagworms. Their name is just as disgusting as they are.
