The Drowned are an underwater variant of zombie that will only spawn underwater, although they can come out of the water if they want to. It is a hostile creature that can be generated naturally or from a drowning zombie. Eliminate Drowned is the only way to get, without tricks, a trident in Minecraft.
Drowned have the ability to perform melee attacks, although if spawned with a trident, they will also be able to perform ranged attacks. Ahogados detest turtles, so they will try to attack them on sight, as well as try to break turtle eggs by stomping on them. Being a zombie variant, it will try to attack villagers, wandering merchants, iron golems and snowmen. If a Drowned One kills a villager by throwing a trident, there is some chance that the villager will become a zombie villager.
Although it is an aquatic creature, the Drowned may sporadically leave the water. If they do, they will always try to find the nearest water source. During the day they will be in the deep sea ignoring players and other creatures. While during the night they will be more active, chasing players and other entities, getting out of the water if necessary. It is worth noting that the Drowned swim as fast as the players, so it will be difficult to outrun them in the water.
These entities can only be generated naturally in oceanic biomes and rivers, in the water. They are always generated at sea floor level, or on the floor of rivers. The Drowned will always spawn with something in their hands, which can be a trident, a fishing rod or a nautilus shell. On rare occasions, a Drowned may even be spawned riding on a chicken, which would be a chicken drowned rider.
For a normal zombie to become a Drowned, it will have to have its head submerged under water for a period of time of 45 seconds. After this time the zombie will begin a process of becoming a Drowned, which consists of a general trembling of the creature. After spending 15 seconds in this state, the zombie will drown and a Drowned will appear.
