Drowned

Drowned are common hostile mobs that generate in all oceans and rivers, or when a zombie drowns.

Naturally
Drowned will naturally spawn at light level of 7 or less in ocean biomes (all variants), and in river biomes.

Drowned have a chance to spawn with either a trident or a fishing rod. They also have a small chance of spawning while riding a chicken, even after drowning as a zombie, creating a drowned chicken jockey.

Conversion
If a zombie is in water (not necessarily underwater) and not in a boat continuously for 30 seconds, it begins the process of converting to a drowned. Once this happens, it will start shaking, a similar effect to when a zombie villager is being cured. At this point the process cannot be stopped, and 15 seconds later the zombie will turn into a drowned.

If a zombie is holding an item when it becomes a drowned, it will drop the item it is holding, whether it spawned with the item naturally or had picked it up, 100% of the time. A zombie that turned into a drowned will also drop all pieces of armor that it wore as a zombie, if any.

Drops
Drowned drop when they die:
 * 0–2.
 * and (2.5% chance each, 3.5% chance with Looting I, 4.5% chance with Looting II and 5.5% chance with Looting III).
 * Any picked-up equipment has 100% chance of dropping and will drop with the same damage level it had when picked up.

Naturally-spawned equipment

 * 15% of drowned will spawn with a
 * 2% of drowned will spawn with a
 * Drowned have an 8.5% chance of dropping their naturally-spawned equipment, and will drop it with a random durability. Each level of Looting will increase the chance 1 percentage point (11.5 % with Looting III).  It is possible for a drowned to drop both its naturally-spawned trident and a second trident as one of its standard drops.

Experience
Drowned will drop 5 experience upon death if killed by the player or a tamed wolf.

Behavior
Drowned have a melee attack, and if they spawn with a trident, they will use it as a ranged weapon including underwater. In the Bedrock Edition drowned with tridents will use a melee attack if the target is 3 blocks or less. They will intentionally stomp on turtle eggs, attack turtles, and like zombies will chase and attack villagers. If on land, drowned will seek out nearby water. They will sometimes step onto land, but will quickly return to the water.

During the day, drowned only swim to attack players that are swimming in the water with them; otherwise, they stay on the floor of the water body they are in, ignoring players that are on land or in a boat. This is because drowned will stay in water to prevent burning in sunlight. However, at night, drowned swim to the surface and will chase players and turtles, even outside the water, like regular zombies, since they cannot burn at that time. The speed of their swim is equal to that of the player.

Trivia

 * Drowned are the only aquatic mobs that are considered undead.
 * A drowned chicken jockey will float to the surface because the chicken it is riding floats, causing the drowned riding it to burn in sunlight during the day, resulting in a chicken in the middle of the ocean or river where the drowned jockey spawned in.
