The Rat (in-game name Rotta)

Rottas are a common enemy in the starting areas of the caves, and can come in a variety of forms further down, each with unique blood fluids like lava or acid.

Doesn't pose much of a threat on their own, but they tend to often aggro gun enemies, which may cause problems, even if the player is invisible. For example, enemies may shoot explosives next to the rat. Very frequent in the Ice Caves. The More Happiness perk mitigates this.
