Usable items

A zombie nautilus is an undead variant of the nautilus that spawns being ridden and controlled by a trident-wielding drowned, forming a zombie nautilus jockey. Once separated from the jockey it behaves like a regular nautilus, but burns in sunlight instead of suffocating while not in water.

Spawning

When an adult drowned spawns outside of river or frozen river biomes, either naturally or as part of a structure (i.e. an underwater ruin), and is wielding a trident in its main hand, it has a 50% chance to spawn as a zombie nautilus jockey, riding a zombie nautilus. Zombie nautilus jockeys thus spawn in dripstone caves and various ocean biomes; those that spawn in warm oceans will become the coral zombie nautilus variant, which apart from appearance is identical to the standard variant.

In this state, the zombie nautilus's movement is controlled by the jockey. When the drowned rider is dismounted or killed, the zombie nautilus becomes neutral. It can then subsequently be tamed and ridden by the player.

Zombie nautiluses do not spawn on Peaceful difficulty, like other monsters.

Drowned:

Zombie Nautiluses behave like regular Nautiluses, drifting through the ocean. They move backward, propelling themselves and leaving bubbles particles behind.

Zombie nautiluses follow players holding any fish or bucket of fish within a 10-block radius.

Unlike the nautilus, zombie nautiluses cannot be bred.

When ridden by a hostile mob, as in the case of a zombie nautilus jockey, the hostile mob controls the movement of the zombie nautilus.

When Vibrant Visuals are enabled, their eyes emit a surrounding glow that does not illuminate objects, just like the glowing eyes of other mobs such as endermen and drowned.

As they are monsters, zombie nautiluses count towards the hostile mob cap, despite this, they are not targeted by iron and snow golems. Parrots can also imitate them, like other hostile mobs.

Attacking

Zombie nautiluses are neutral, attacking only when provoked. Like regular nautiluses, they attack by dashing into their target. Zombie nautiluses occasionally dash toward and attack nearby pufferfish.

When dashing toward a target on land, zombie nautiluses can launch themselves out of the water and accidentally become beached on the land where they are unable to move.

They may also unintentionally attack a mob or player that stands between them and their target.

A zombie nautilus can also perform dash attacks when being ridden by a mob, such as when part of a zombie nautilus jockey. It performs dash attacks on its own accord, temporarily taking control of the jockey's movement.

Taming

Zombie nautiluses can be tamed by being fed pufferfish or buckets of pufferfish. These items can also be used to tempt them.

Healing

Zombie Nautiluses can be healed by being fed any fish or any bucket of fish.

Mob type

Being an undead mob, they are:

Like most other undead mobs, zombie nautiluses also burn in direct sunlight. They are protected from burning when wearing nautilus armor, similar to other undead mobs wearing helmets. As nautilus armor has no durability, it does not break from absorbing the damage like helmets do.

Being an aquatic mob, they are affected by the Impaling enchantment on Java Edition. Unlike the normal nautilus, zombie nautiluses don't suffocate outside of water, as they are undead monsters.

In Bedrock Edition, zombie nautiluses prevent the player from sleeping and are killed by the conduit like any regular hostile mob.

Weaknesses

Like regular nautiluses, they can be controlled and even dash on land, but their movement is much slower than in water.

Usage

Tamed and saddled zombie nautiluses can be used as a means of underwater transportation. When ridden, the player is granted the Breath of the Nautilus status effect, which pauses the oxygen bar while the player rides the zombie nautilus. As with other zombies, they can be killed to obtain rotten flesh.

Equipment

Tamed zombie nautiluses can be equipped with a saddle and nautilus armor.

Equipment can be placed on a zombie nautilus by holding it and then using it on the zombie nautilus.

The equipment can be removed by using shears on the zombie nautilus. If both a saddle and nautilus armor are equipped, they are removed one at a time. The first use removes the nautilus armor, and a second use removes the saddle.

Riding

Once a zombie nautilus is tamed and saddled, it can be ridden by the player. Like nautiluses, the zombie nautilus can be controlled with standard directional controls, jump, and the mouse. The player dismounts using the dismount control. Zombie nautiluses also have a "dash" ability similar to the nautilus, camel or camel husk. The dash is controlled by the jump control and dashing while moving upwards near the surface results in a quick breach, wherein the zombie nautilus and the player riding it break the surface briefly. Holding the jump control charges for a longer dash.

Zombie nautiluses are 10%~ faster than nautiluses when swimming.
