Can Mobs Spawn in 1 Block of Water?

In this article, we will explore the answer to a commonly asked question in Minecraft’s vast and wondrous world: "Can mobs spawn in 1 block of water?"

Regular Spawning Mechanics

In Minecraft, mobs (monsters) don’t spawn in water. Regular spawns apparently cannot spawn in or on any kind of water; Mobs need to spawn on solid gray blocks, not air, translucent blocks, or full blocks of water. So, no.
They only spawn on non-water blocks, which include ordinary stone, gravel, dirt, and several others.

Waterlogged Areas and the Exception

However, even with waterlogged areas containing no full blocks of water, only mob spawners (like ghasts and blaze) can spawn in these wet regions. Mobs spawned outside the spawners behave according to regular spawning rules, not liking transparent water blocks.

Drowners, a Special Kind of Spawn

Drowning mobs have an exception due to the new aquatic biome concept, specifically designed for those under-water environments. Straylings and Dronquints (or various other mobs) sometimes generate underwater in seaside environments or oceans (1 block below sea floor). However, these exceptions are limited (like spawning below sea floors only).

Other Insignificant Facts

• Ice and Frosty Blocks : These translucent blocks don’t repel spawning.
• Air block gaps (1-square, at least) separating full blocks (like water).

Spawn Restrictions

Here you have an outline of the water-to-spawn restrictions list (more specific details regarding restrictions).

Can Mobs Spawn on Waterlogged But Full Water Blocks?

No : Allowing Waterlogged block without Full Water Block; yet only in specific Drowners cases. Rare Ocean/Marine Bioms exception below sea floor/ Sea Floor (1 block subwater, but not entirely)

Mobs don’t take care about waterlogged stones or half-blocks inside buildings as long as none contain solid water blocks. We hope the article has become useful; to better understand "waterlogged areas" by having examples.
