My wife and I have slowly come up with nicknames for the various nasties. Can you guess which is which? I won’t add Crabchaps, too obvious. Also - does anyone else have any good ones? 
Larry, Curly, and Moe

Don’t have any nicknames, but nicknaming the enemies and their mutation combinations will be a feature in the final game. Unless that has been changed that is.
They get lots of nicknames midmission, but most of them would make the word filter explode.
