Rot

"Everything turns to waste eventually."

- Wendy

Rot is produced when Food items (excluding Eggs) spoil. Rot can be used as Fertilizer for Farming (e.g. for Basic Farms, Improved Farms, Grass Tufts, and Berry Bushes) or it can be used as a source of Fuel.

Some Mobs, such as Pigs or Smallish Tallbirds, will eat Rot left on the ground, but they cannot be given rot directly. Since Rot doesn't restore any Health or Hunger to Mobs, they are able to consume an infinite amount of Rot left on the ground.

Bees in inventory can be fed with rot.

Rot may appear along with items (such as Rope and Bird Traps) in a Set Piece, near a Chest and/or Backpack. Opening either container will cause the player's perishable items to turn to Rot, though this can be avoided by dropping the items a distance away first.

Tips

 * A quick way to obtain Rot is to leave Roasted Berries or Fish lying on the ground (preferably in a walled in area, so that animals can't eat them).
 * WX-78 can eat spoiled food, but will still be damaged by eating Rot.
 * A Tallbird nest near a Rabbit Hole (or other areas where weak mobs spawn) is a good source of Rot.

Trivia

 * Fertilizer properties: 4 Rot = 1 Manure; 5 Rot = 1 Guano.
 * Rot originally looked like a blue ball. Though the texture is now a misshapen blob, multiple characters still refer to it as a "ball".
 * The food with the shortest perish time is Lichen, turning to Rot after just 2 days. The food with the longest perish time is the Powdercake, which turns to Rot after 18,750 days.
