Cocoa

Cocoa Plants are plants which grow on Jungle Logs, and are found naturally on the trunk of naturally grown normal-sized jungle trees. The player can harvest Cocoa Beans from them.

Farming
The player is able to plant Cocoa Beans on the side of jungle tree logs. The Cocoa Plant has three stages of growth. During its first, the pod is small and green. In the second stage, the plant is bigger and colored tan. In its last stage, the pod is even bigger and orange. When destroyed in the first two stages, the plant will only yield one Cocoa Bean. When destroyed in the third stage, it will give three Cocoa Beans. Bone meal can be used to immediately mature the Cocoa Plant to its last stage of growth. If a piston pushes the wood that the pod is on, then the pod will break and drop the cocoa.

History
Jeb revealed Cocoa Plants on May 8, 2012 with a screenshot.

Cocoa Plants were made public in Minecraft Snapshot 12w19a on May 10, 2012.

Trivia

 * Before snapshot 12w21a, using the Pick Block button on Cocoa Plants will give the item "Cocoa", which can be placed anywhere as small Cocoa Plants. After this snapshot, it will give the correct item "Cocoa Beans".
 * The player can stand on Cocoa Plants. If a cocoa plant grows while the player is standing next to it, the player will not be pushed out and can move through it.
 * Player-created Jungle Trees do not generate with Cocoa Beans on them.
 * Cocoa Plants do not drop more Cocoa Beans if a tool enchanted with Fortune is used to destroy them.
 * Water can break Cocoa Plants if the water flows onto them. This also happens when the jungle wood block that the plants are attached to is moved by a piston, allowing the player to make semi-automatic Cocoa Bean Farms.
 * Cocoa plants faintly glow.
