Hibernation

Hibernation is accomplished once your Slugcat has gathered four points worth of food and entered a hibernation chamber. Once the chamber has been entered, the entrance will be sealed and your Slugcat will enter hibernation. Note that the chamber will not seal if you do not have the required four points of food.

Herbivorous Food Sources

 * Pupa Fruit/Blue Fruit - Brightly colored orbs that are described as "delicious" and grow from ceiling vines. After hibernation, these fruit may regrow from the same vines. Found in every region of the game except Five Pebbles.
 * Water Popper/Bubble Fruit - Blue spheres 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 popcorn. Scavengers will also eat these and may challenge Slugcat for possession of them. Found in Shoreline, Garbage Wastes, Shaded Citadel, Industrial Complex, Subterranean, Drainage System, and the Farm Arrays
 * Popcorn Plant - After being hit with a spear, small kernels will emerge from the plant and act as a source of unlimited food. The plant wilts after one hibernation after being cracked open, and will take several cycles to regrow. Found in Industrial Complex, Garbage Wastes, Shoreline, Farm Arrays, Sky Islands, Chimney Canopy, and the Outskirts.
 * Orange Mold - Orange Globs of Jelly that glow softly and will steadily replenish every few cycles. Found exclusively in Shaded Citadel and The Exterior.

Carnivorous Food Source

 * Bats - The most common source of food, Live Bats can be eaten for one food point each. Similarly to Pupa Fruit, they are found in every region except Five Pebbles.
 * Vulture Grubs - Dead Vulture Grubs can be eaten, they can usually be found in proximity to live ones, which can then be killed and eaten using a weapon. Found in Garbage Wastes, Industrial Complex, Farm Arrays, and Chimney Canopy.
 * Centipedes - Dead Centipedes act as a source of food after being killed, the amount of food depending on the length of the centipede, with infants being worth 2 food points and the largest adults worth 12-14. Found in Drainage System, Outskirts, Farm Arrays, Garbage Wastes, Industrial Complex, Shaded Citadel, and the Sky Islands. Centipede subspecies such as Flying and Red Centipedes can also be consumed.
 * Neuron Flies - Live Neuron Flies can be eaten for one food point and will give the player a permanent radiant glow that is useful in dark areas when eaten for the first time. Found in Five Pebbles and Shoreline´s subregion Looks to the Moon, though Neurons eaten in Looks to the Moon will never respawn.
