Ah, not ordinary rats, I see.  The ordinary brown rat is also called the sewer rat, so I made a connection there.  The rat king influence was meant to be represented by the friend attack triggers.

I had thought the lore dictated that ooze did not affect mammals that were below a certain size?  Is that wrong, or are these rats an exception?  If the ooze can _mutate_ a smaller animal rather than zombifying it, then we could have vicious mutant cats and bats and mice and other horrible little things.
