Rabbit

Rabbits or Bunnies are mobs created by Ryan Holtz. Rabbits are passive and bounce around aimlessly.

Rabbits were initially proposed by Notch during Survival Test development, but the plan was quickly dropped. Five years later, Holtz posted an image of rabbits in game with a statement that he created them solely for amusement and was not intended to be added in Minecraft. Later however, Holtz revealed that the mob is in production and it would be added in the game.

Drops
Rabbits have three known drops. They drop rabbit hides which can be crafted into leather. They also drop raw rabbit meat, which can be cooked. They can also drop rabbit's feet which can be brewed to create potions of Leaping.

Variants
Rabbits will have different skins, but it's unknown how many skins exist.

There is a 1 in 1000 chance that a rabbit will spawn hostile and be named "The Killer Rabbit of Caerbannog". This is an easter egg based off of the Rabbit of Caerbannog from the British comedy film, Monty Python and the Holy Grail.

Spawning a Rabbit named 'Toast' using a name tag or renamed Spawn Egg will give the rabbit the skin of Reddit user xyzen420's girlfriend's missing rabbit, as a memorial.
