Observed Result
Water flows over the block where the conditions are right for Creaking to spawn, but Creaking spawns.
Enemy ground mobs cannot spawn in the presence of water, is this correct behaviour for Creaking to be able to spawn?
I want to use this in my device, so I need to check.
Thanks for your comment, EldesRed!
I reported whether they spawn in water-filled rooms, as I could not find them as far as I could check.
Does this seem to be OK?
Can it spawn in water with the same specifications as a Drowned?
