I has checked Drowned entity and i found a bug. Drowned do not attack villager and player without water/only air while sun. But Drowned can attack villager and player with water. Zombie is normally a Minecraft enemy can attack villager and player but can burned in sun. Drowned is the drown zombie while you drowning zombie and it shake, Drowned do not attack a villager while sun and without water/air. Enjoy that bug!
