hostile nocturnal mobs

In hard mode difficulty Spiders are hostile at night in darkness but neutral in the daylight. Untamed Wolves should also be hostile at night and neutral in the day, but they could be calmed down when the player holds meat and or feeds them meat or a bone, to tame them they can't be aggressive. also just like how wolves kill sheep, spiders should hunt pigs or cows. just like polar bears the untamed wolves should become hostile when the player is near a baby wolf. Also they should have an animation to howel at the moon regularly depending on the moon phase with full moon being the most. in real life it's very dangerous to interact with wild wolves but even if Minecraft is a game it should still show wolves as dangerous to people. also if this feature is only in hard mode the default game normal difficulty is how it always was.
