This is a rat king

Mice and rats can be gentle kind lovely animals. BUT when in a large group can be EXTREMELY SCARY!!!

I thought the biggest one was in tmnt

I saw this in teen woft (it's a pretty okay series)
And instead of dry rats, I saw a puddle (yes, a puddle) of living rats twisted together in dirty water.
It was so disgusting

This is wholly unpleasant concept and image.

Didn't terry pratchet write a book with one of these in it?
