Sheepig

Mangalica (or sheepig) is a neutral mob that serves as a source of wool and porkchop.He spawns in all types of snowy taiga, has a baby version. Mangalitca will attack the player if he makes a sharp movement next to her or approaches the sheepig baby. It is fashionable to cut it with scissors, while 1-3 wool will drop, when killed, 0-2 wool and 1-4 raw porkchop (or cooked, if died from fire) will drop. I think that would diversify the game, and add an additional source of wool.
