Rabbit

Rabbits or Bunnies are passive (with one rare exception) mobs. They spawn in many different biomes and, unlike most other mobs, hop around instead of walking.

Spawning
Rabbits naturally spawn in plains, extreme hills, forest, taiga, swamp, jungle, birch forest, roofed forest, cold taiga, mega taiga, and savanna biomes. They usually spawn in groups of three; one adult and two babies.

Behavior
Rabbits are moderately fast, hopping around aimlessly. They will approach players holding carrots, and will turn to look at players from a much farther distance than other mobs. Like other passive mobs, they will run around aimlessly in a panic if you hit them.

Rabbits will find and destroy mature carrot crops, requiring that your carrots be surrounded by fencing in biomes where rabbits spawn.

Wolves will track down and kill any rabbits. Most rabbits will quickly run away from all nearby wolves. Tamed wolves will not give chase, however, unless you were to hit the rabbit first.

Breeding
Rabbits can be bred with the use of carrots, golden carrots, or dandelions, but only carrots will cause rabbits to follow the player until 1.8.1-pre1. If you used carrots for breeding, the rabbits will continue to follow the player and ignore being under the breeding effect as long as you are holding a carrot. Select another item to hold, or an empty hand, and the rabbits will path to each other and mate. Baby rabbits will have the same type of fur as the first of the two parents you fed (typically, the one from which it spawns). Baby rabbits will grow up after 20 minutes.

The growth of baby rabbits can be slowly accelerated using carrots. Each use takes 10% off the remaining time to grow up.

Killer Bunnies can breed with other rabbits, and with each other.

Variations


Rabbits will typically spawn using one of 6 different skins. Skins include regular brown fur, black mottled fur, white fur with red eyes (Albino), black & white spotted fur, salt & pepper fur, and gold (cream) fur.

There are 2 rare variants of rabbits:

The Killer Bunny


The Killer Bunny is a variant of the rabbit that is hostile to all players. Its fur is pure white with blood-red eyes that are horizontal, compared to a normal rabbit's vertical eyes.

If the Killer Bunny finds any player within a 15 block radius, it will hop very quickly towards the player, much faster than a normal rabbit. It moves in a style similar to that of a spider. Once it closes in, it will lunge at the player, dealing a fair amount of damage. If the player strikes at the Killer Bunny, it will run away for a brief moment, then return to lunging at the player.

If it cannot find a player, the Killer Bunny will actively seek out and attack any wolves as well, including tamed dogs. These wolves will, in turn, attack the Killer Bunny, leading to a vicious fight. Therefore, when fighting the Killer Bunny, it is wise to bring several wolves along with you, whether or not they are tame, as they will help you with defeating this rabbit.

On peaceful difficulty, the Killer Bunny will not despawn, regardless of its hostile nature. It will still attack wolves and pet dogs.



Toast
Naming a rabbit "Toast" using either a name tag or a named spawn egg will turn it into "Toast". Toast is textured like a black dutch, with a large black & white patch and more black fur around the face than the natural black & white spotted rabbit. Other than its name and skin, Toast behaves exactly like a normal rabbit.

This rabbit is the skin of user xyZenTV's girlfriend's missing rabbit, which Ryan Holtz implemented as a memorial.

Data values
When using the command to spawn a rabbit, the NBT value RabbitType will determine which variation to use. For example the Killer Bunny can be summoned with the command. Likewise, a baby Killer Bunny can be spawned by typing.

Toast does not seem to have a data value. It must be summoned using

Drops
Rabbits have three drops. They drop rabbit hides, raw rabbit, and rarely a rabbit's foot. Therefore, rabbits are currently the only natural source of ingredients for a Potion of Leaping.

If they die while on fire, they will drop cooked rabbit instead of raw rabbit.

Trivia

 * Rabbits can also be fed dandelions, possibly because Ryan Holtz fed a rabbit dandelion leaves while mini-golfing.
 * The Killer Bunny is a reference to the Killer Rabbit of Caerbannog from the British comedy film Monty Python and the Holy Grail.
 * The Killer Bunny was suggested by Twitter user @88bully
 * If you rename the Killer Rabbit to Toast, it will still be hostile while appearing to be passive.
