Slugcat

The mega-cute Slugcat is both the primary protagonist and single playable character in Rain World. It is a small white creature with black eyes, thin arms, comparatively broad legs with small feet, pointed ears, and a thick tail that tapers to a point. The player must keep the Slugcat alive as they explore the World, confront strange Creatures, and take part in challenging Quests.

Abilities
As one of the weaker creatures in the food chain, Slugcat is still capable of certain survival abilities.

Slugcat is also followed around by a strange golden being that will provide tips via holographic-like images.
 * Walk/Run/Crawl - With its flexible and agile body, Slugcat can squeeze through small pipes that crisscross the entire map and travel across the foreground on either two paws or four.
 * Climb - Slugcat can climb poles and other various objects to escape from enemies.
 * Sneak - In order to evade predators, Slugcat can crouch and sneak to prevent being noticed.
 * Jump
 * Swim
 * Pounce - Slugcat can crouch on ledges to leap that extra distance for bigger gaps.
 * Carry and throw items (including weapons such as spears or rocks, food, and other items) - Slugcat can hold a total of 3 items, one in each paw and one in its mouth that can be regurgitated for later use.

Food
In order to survive, Slugcat must continue to eat whatever is available in the harsh landscape.

Herbivorous Food Sources

 * Blue Fruit - brightly colored pear shaped fruits that are described as "delicious" and grow from ceiling vines. After hibernation, these fruit may regrow from the same vines.
 * Bubble Fruit - blue circles ringed in grey, the seeds grow from short sprouts on the ground and must be thrown into water before becoming edible. When watered, the seeds will 'pop' into a white fruit visibly similar to a bubble. Scavengers will also eat these and may challenge Slugcat for possession of them.

Carnivorous Food Sources

 * Flies - These both spawn and despawn from nests littered about the world. They are difficult to catch, and if even just one is eaten before hibernation, they will disappear on the next cycle.
 * Bats - The most common source of food for Slugcat, small bats will fly in groups of 3 or more between rooms. They are difficult to catch but are the most plentiful.
 * Banana Slugs - Dead Banana Slugs can be eaten, they can usually be found in proximity to alive ones.
 * Centipedes - The centipede is a nimble navigator; small centipedes are relatively harmless, but must be picked up and eaten immediately, or else they will stun Slugcat with electricity. Large centipedes will attempt to kill and eat Slugcat, but once killed, become an unlimited food source for Slugcat.

Slugcat Pups
It has been confirmed there will be Slugcat "pups" for you to take care of. They come in four colors: Slugcat Pups are said to be only mildly intelligent, so handling them is presumed to be very hard.
 * Yellow
 * Green
 * White
 * Black

It is also said that if you neglect or treat the Pups badly, they will abandon you... or worse. The Developers say the Green Pup is the most dangerous.

 Note: It is said that you might be able to get them for the Playstation versions but it is unknown if you can get them for the PC versions since the world is not fully explored but if not perhaps it shall be available in the next update.

Multiplayer
It has been confirmed that there will be a co-op/multiplayer mode.(though it might only be local and not online)

It is rumoured that Player 2 will be able to choose their Slugcat's color, from the colors yellow, green, pink and black.
