Crows & Rats

[Rodimus]

Add Crows as either quest-givers or animal companions.
Can be a good source of INT when butchered. Will aggro as a group.
Crow Credo that allows you to remotely guide Crows in a limited area.

Rats become breedable and can be housed in Terratium. Can spawn an aggressive variant called Mad Mouse, which will always spawn outside the rat housing and stay for several hours.
Rat Dungeons that are as complex as Bee Dungeons.
Rat King, aggressive dungeon boss. Drops King Tail and King Tooth which can be studied or used as recipes for other curios/elixirs.
And Rat King, a curio made from several rats adjoined together by their tail.
Rats now also spawn near containers, such as granaries or cupboards. Greater chance with food-related items.
Rat Credo that basically stops Rats from spawning on your claim.
