Minecraft 1.21.11 Mounts of Mayhem: Everything You Need to Know
The wait is over! Minecraft 1.21.11, officially named Mounts of Mayhem, dropped on December 9, 2025, bringing an exciting wave of new content focused on rideable mobs, combat weapons, and underwater exploration. This guide covers everything you need to know about the latest Minecraft update.
What is Mounts of Mayhem?
Mounts of Mayhem is the fourth "Game Drop" of 2025, following Mojang's new approach of releasing smaller, more frequent updates throughout the year instead of one large annual update. This drop focuses heavily on new mounts and combat mechanics.
New Mobs: Nautilus and Zombie Nautilus
The Nautilus
The star of this update is the beautiful nautilus - a new aquatic mob that can be tamed and ridden! Here's what you need to know:
- Taming: Feed a nautilus pufferfish to tame it
- Mounting: Once tamed, equip a saddle to ride it
- Breath of the Nautilus: While riding, your oxygen consumption is paused - perfect for ocean exploration!
- Armor: Nautilus armor comes in five tiers: Copper, Iron, Gold, Diamond, and Netherite
Zombie Nautilus
The undead variant lurks in the ocean depths:
- Often found with a trident-wielding drowned rider
- To tame one, defeat the drowned rider first
- Then tempt it with pufferfish like the regular nautilus
Zombie Horses Are Finally Here!
After years of being unobtainable in survival mode, zombie horses now spawn naturally:
- Spawn Location: Plains and savanna biomes
- Behavior: Spawn in darkness, burn in sunlight (like other undead)
- Zombie Horsemen: They spawn with a zombie rider holding an iron spear
- Taming: Tame them like regular horses
- Healing: Use Red Mushrooms to heal and tempt them
- Equipment: Can wear saddles and horse armor (which protects from sunlight!)
New Weapon: Spears
Spears are a brand new weapon type available in all material tiers:
Spear Attacks
- Jab Attack: Keep enemies at distance while on foot, pushes them back
- Charge Attack: Perfect for mounted combat, based on precision and speed
Lunge Enchantment
A new exclusive enchantment for spears that gives you a burst of speed - great for combat or quick travel!
Mob Spear Usage
- Piglins can now spawn holding golden spears
- Zombies and Husks can spawn with iron spears
Netherite Horse Armor
Finally! You can now craft Netherite Horse Armor to give your trusty steed the ultimate protection. Perfect for those dangerous Nether expeditions with your horse.
Desert Dangers: Camel Husks and The Parched
New hostile mobs roam the desert biomes:
Camel Husk
A camel ridden by TWO hostile mobs:
- A Husk with a spear
- A Parched - a new desert skeleton
The Parched
This new skeleton variant fires devastating arrows that apply the Weakness effect. Watch out when exploring desert temples!
