Goats addon is an easy way to meet a new creature that has been announced for Cave and Cliffs update. You can meet those creatures in a high hills biome or on basically any snowy mountain. In such a harsh climate, goats are a good source of food and wool. You can build a farm and breed goats for your needs - just feed them with wheat. Goat can also drop a Goat horn - an item that can be blown to apply a bad omen effect on a character for 8 seconds. The last important thing to mention is that goats can spawn in one of four variants - white wool, grey, brown, and black.
