Mounts of Mayhem
‘Mounts of Mayhem’ rides in as Minecraft’s fourth game drop of 2025, putting momentum and mounts front and center. The update launched on December 9, 2025 as Java Edition 1.21.11 and Bedrock Edition 1.21.130, adding a brand-new tiered weapon called the spear, overhauling mounted combat across several biomes, and introducing the nautilus as the first tameable underwater mount in vanilla survival. Zombie horses finally spawn naturally, desert zones get the camel husk and the parched, and most existing mounts can now swim. This overview covers what is in the ‘Mounts of Mayhem’ update and what that means for your server.
Overview Mounts of Mayhem:
Holiday Drop: The ‘Mounts of Mayhem’ Update
‘Mounts of Mayhem’ is a Minecraft game drop themed around mounted combat and travel, both on land and underwater. Internally, Mojang refers to it as the ‘Holiday Drop 2025’ and it is the fourth of four drops released in 2025, following the ‘Copper Age’ drop earlier that year. The update was first revealed at Minecraft Live in September 2025.
The ‘Mounts of Mayhem’ update adds new mobs that either act as mounts, ride mounts, or both, including:
- nautilus
- zombie nautilus
- zombie horse
- camel husk
- parched
It also introduces:
- the spear as a new melee weapon
- two new armor types (nautilus armor and netherite horse armor)
- saddle charms
- decorative saddles
- a new structure called spear trials
Most existing mounts can now swim while being ridden, which opens up a lot of new travel routes.

New ‘Mounts of Mayhem’ Mobs
Minecraft ‘Mounts of Mayhem’ adds five new mob types and changes the spawning behavior of the zombie horse. The short summary: every new mob is either a mount, a rider, or a pairing of both. The following subsections cover each one briefly.
Minecraft Nautilus
Meet the nautilus: the first tameable underwater mount in vanilla Minecraft. It is a passive mob that spawns in cold and deep ocean biomes, can be tamed by feeding it pufferfish, and ridden with a saddle. While riding a tamed nautilus, the player gains the breath of the nautilus effect, which pauses oxygen depletion (but does not refill the air bubbles). Two tamed, healed nautiluses can also be bred using any fish.
Minecraft Zombie Nautilus
The zombie nautilus is the hostile counterpart found in oceans, usually ridden by a drowned wielding a trident. Unseating the rider and feeding the mob pufferfish lets the player tame and ride it. Unlike the nautilus, the zombie nautilus can leave the water briefly and nautilus armor prevents it from burning in sunlight.
Minecraft Zombie Horse
In Minecraft, light and shadow often share the same pasture and with ‘Mounts of Mayhem’, that is finally true for horses too. The zombie horse previously only existed in creative mode. It now spawns naturally at night in plains and savanna biomes, always paired with a zombie rider holding an iron spear. This pair is called a zombie horseman. Zombie horses burn in direct sunlight like other undead mobs, so keep them in shade, tunnels, or under a roof once tamed. The mount itself is passive and can be tamed and saddled like a regular horse after dismounting the rider.
Minecraft Camel Husk
The camel husk is a new desert mount that spawns with two hostile riders: a husk wielding a spear and a parched. It does not burn in sunlight and can be ridden once both riders are dealt with, but it can’t be tamed or bred through normal means. It can, however, be healed with rabbit feet, its preferred food.
Minecraft Parched
The parched is a new skeleton variant that spawns in desert biomes at night. It does not burn in sunlight (but does not spawn in caves), and it fires arrows of weakness. The parched also appears as the second rider on a camel husk, making desert nights significantly more dangerous.
Items & Gear in ‘Mounts of Mayhem’
On the item side, ‘Mounts of Mayhem’ adds a new tiered weapon, two new armor types, and cosmetic saddle additions. The short version:
- spear – new tiered melee weapon
- nautilus armor – gear for a tamed nautilus
- netherite horse armor – final horse armor tier
- saddle charms & decorative saddles
The Spear
The spear is a tiered weapon with 7 variants:
It has two attack modes: a jab (a fast thrust with slight knockback) and a charge attack, whose damage scales with the player’s movement speed. The spear also comes with a unique enchantment called lunge, which grants a short burst of speed on the jab. Certain hostile mobs (including zombies, piglins, husks and zombie horsemen) can spawn holding spears.
The Nautilus Armor
Nautilus armor is a new gear type that can only be equipped on a tamed nautilus or zombie nautilus. It can’t be crafted directly: the copper, iron, gold, and diamond variants are found in naturally generated chests inside buried treasure, ocean ruins, and shipwrecks. The netherite variant is obtained by upgrading the diamond variant on a smithing table with a netherite upgrade template and 1x netherite ingot. Nautilus armor also prevents a zombie nautilus from burning when exposed to sunlight.
The Netherite Horse Armor
Netherite horse armor is the final tier of horse armor. It is obtained by upgrading diamond horse armor at a smithing table with a netherite upgrade template and 1x netherite ingot. It provides 19 armor points, 3 armor toughness, and 1 knockback resistance, and it is currently the strongest protection available for a tamed horse.
New Mechanics & Structures in ‘Mounts of Mayhem’
Beyond items and mobs, ‘Mounts of Mayhem’ introduces several mechanical changes that affect how players interact with mounts in general. Before listing each one individually, the key areas to note are:
- mount-based combat scaling
- mounts that can swim
- the spear trials structure
Mounted Combat With the Spear
The spear’s charge attack is the first melee mechanic that directly rewards the rider’s momentum: the faster a mount is moving when the charge lands, the more damage it deals. This works for horses, camels, and even an Elytra dive or a speeding minecart. A charged spear hit can also knock riders off their own mounts.
Swimming Mounts
Most mounts in ‘Mounts of Mayhem’ no longer sink when a player is riding them through water. Riders are still dismounted when their own head goes fully underwater, but the mount itself now stays afloat. This change applies to:
- horses
- donkeys
- mules
- most other rideable mobs
It does, however, not apply to saddled pigs.
Spear Trials
Spear trials is a new structure added by the ‘Mounts of Mayhem’ update. It follows the trial-style format used by earlier drops (similar to trial chambers) and focuses on mounted spear combat scenarios. Loot includes spear-related items and saddle charms.
FAQ
‘Mounts of Mayhem’ is a Minecraft game drop released on December 9, 2025 as Java Edition 1.21.11 and Bedrock Edition 1.21.130. It focuses on mounted combat and travel across land and sea. The main additions are the spear, the nautilus and zombie nautilus, zombie horses spawning naturally, the camel husk, the parched, nautilus armor, netherite horse armor, saddle charms, decorative saddles and the spear trials structure.
They spawn naturally in plains and savanna biomes at night, always with a zombie rider holding an iron spear.
To tame a nautilus, you need to feed it pufferfish, then apply a saddle to ride it. For the zombie nautilus, first defeat the drowned rider, then feed pufferfish.
The nautilus is a rideable mob added in ‘Mounts of Mayhem’. The nautilus shell is a crafting item that has existed since the ‘Update Aquatic’ and is used in recipes such as the conduit.
No new biomes were added, but the desert biome received significant mob updates (camel husk, parched) and oceans gained new underwater mounts and hostile mobs.
Saddle Up for ‘Mounts of Mayhem’ on Your GPORTAL Server
‘Mounts of Mayhem’ is one of the biggest shifts to Minecraft’s combat and traversal systems in years. Mobility itself becomes part of the power curve. On land, the spear turns raw speed into damage, while zombie horsemen and camel husks raise the stakes of every ride across plains, savanna and desert. At sea, the nautilus opens up sustained ocean exploration for the first time. Because mounts now sit at the center of both combat and travel, the update rewards groups who coordinate – which is where a private server comes in.
Running the latest version on a stable, managed server means no waiting for a friend’s world to come online, no lost nautilus progress, and no arguments over whose PC hosts tonight’s session. Set up your own Minecraft server from GPORTAL, update to 1.21.11, and charge into ‘Mounts of Mayhem’ with your friends.
