Mystical World adds a ton of new creatures to Minecraft. It makes the world a bit more immersive and most of them can be tamed offering a greater variety of companionship and protection in the game. Foxes are typically aggressive to chickens and rabbits so keep watch of any you have at your bases. But they can be tamed and help you similarly to wolves. You may also encounter deer and stags in forests. They drop venison and leather but otherwise are an adorable feature to wooded areas. Sprouts are cute little plant-looking creatures that offer a variety of drops like potatoes and melons! And silkworms are a new way to obtain string. When you break leaves you may get silkworm eggs that can be hatched and then over time they will form a silk cocoon that can be converted to silk thread.
