The niffler currently chewing on underwear paid no mind to the new human who had appeared. He began to dig in the drawer sniffing around for shinies while he chewed on the underwear.

Another niffler dug into the contents of someone's trunk, pulling out a metal chain of some sort. The nifflers were finding their shinies, yes, and quickly gathering together to begin their search for MOREEEEEE SHINIIIIIIIES when with a CLANK one of their brethren had been trapped in the drawer.

It scared a few of the nifflers enough to run right out of the dorms, but still others remained, tearing apart beds, trunks, dressers. The one trapped merely scratched at the wood. It whined.

It whined more.

It peed.
