Between all the building and mining, Minecraft gives you a lot of freedom to wander around and discover all sorts of mobs. Some are passive, some will try to attack you, and some can even be tamed.

Nautilus is a brand new underwater rideable mob in Minecraft Mounts of Mayhem. After the update, this mob will have a 50% chance of spawning in cold, deep cold, frozen, and deep frozen ocean biomes.
