Cloth Barnacles

In all of the ways to be embarrassed in the world of Remnant and out of all the Grimm in it: the Cloth Barnacle is easily at the top of the list of ways for a person to stay away from lest they want to be embarrassed. They are a neutral creature that isn't harmful in anyway, in fact: some rich folk actually keep them as pets. But what makes them so dreadful is the fact once they latch on to any form of state of dress, whether it be one's shirt or undergarment, they don't stop spreading until every last piece of cloth the unfortunate victim wears has been completely devoured.

As such; these things have been labled illegal to use as it can easily be considered a perverts dream pet or a pranksters ultimate tool. Worst part is that no real weakness has been discovered yet; making it a first priority to remove the affected garment as fast as possible. Possible frontal or lower nudity be damned.
