This is the "evil"counterpart of rabbits.....The Killer Rabbit of Caerbannog

There is a 1 in 1000 chance that a rabbit will spawn hostile, and attack players who come within four blocks. This rabbit is referred to as "The Killer Rabbit of Caerbannog" in the player death screen. This is a reference to the Rabbit of Caerbannog from the British comedy film, Monty Python and the Holy Grail. In Peaceful difficulty, the killer rabbit will not despawn and will still try to attack players, but will do no damage.

Now with "save ink" version: NOTE: For a realistic look cut black lines on the parts (exept the flaps)
