The playable character species of the game Rain World.
Salient qualities are smooth, usually monochromatic skin with solid eyes, a thick tail, and the ability to use simple tools.
The base game has three different playable slugcats:
Survivor (white) - The baseline experience. Survivor has no special attributes and average stats.
Monk (yellow) - Slightly decreases the difficulty level. The game is otherwise the same.
Hunter (pink) - Greatly increases the difficulty. The game is also changed significantly, with both the player's start position and the end goal being different.
The "Downpour" DLC adds five more playable slugcats, all with unique campaigns, plus one secret slugcat. The game world also undergoes changes between campaigns, sometimes slightly, sometimes tremendously.
Gourmand (orange) - A more... rotund slugcat than most.
Spearmaster (purple, with white spots on tail) - Can produce spears on demand. Has no mouth.
Rivulet (light blue, with axolotl-like "whiskers") - Runs and swims extremely fast. They'll need it.
Saint (green) - Nonviolent, vegetarian, and more than what they seem.
Inv (black) - Secret slugcat. More or less a joke, as their campaign contains various fourth-wall breaking elements and the difficulty is ramped to absurd levels. On the plus side, they start with a singularity bomb.
