Apart from the normal aquatic mob that spawns in the biome where the ruin is, up to four drowneds are spawned close to them. If the player is trying to collect the loot from the ruin's chests, they will most likely have to fight them. Drowneds are a variant of zombies that spawn only underwater in ocean and river biomes.
