Drowned

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

Natural generation
Drowned will naturally spawn at light level of 7 or less in ocean biomes (all variants) and in river biomes. They spawn at the bottom of the body of water they are in, and walk on the bottom instead of swimming like other mobs.

Drowned have a chance to spawn with either a trident or a fishing rod, and occasionally with a nautilus shell. They also have a small chance of spawning while riding a chicken, even after drowning as a zombie, creating a drowned chicken jockey. They can not spawn naturally with any armor, unlike its other zombie counterparts.

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 or wearing an item when it becomes a drowned, it will drop the item it is holding or wearing, 100% of the time if it had picked the item up, or the normal 8.5% +1% per looting level if it spawned with the item naturally. Zombie villagers do not transform, and husks will not transform instantly, instead transforming into a regular zombie as a midway point.

Drops
Drowned drop when they die:

 * Any picked-up equipment has 100% chance of dropping and will drop with the same damage level it had when picked up.

Experience
Drowned will drop 5 experience upon death if killed by the player or a tamed wolf (or 12 if it is a baby).

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 away or less. They will intentionally stomp on turtle eggs, attack baby turtles, and like zombies will chase and attack villagers and iron golems. 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. They remain passive to players not in contact with water and will not attack them during the day only. 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 as well as baby 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.

If a drowned kills a villager with a thrown trident, the villager has a chance of turning into a zombie villager instead of dying.

Data values
Drowned have entity data associated with them that contain various properties of the mob. Their entity ID is.

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.
 * Drowned are immune to damage from Guardians and Elder Guardians' lasers and thorns.
