Iron golem

The Iron Golem could theoretically have a fury, likewise in the famous game Clash royale, that it would grow a little stronger for a few seconds when a villager died within a reasonably reasonable radius of it, with red eyes and its angry monk. they can also add a new designer for him when he enters the water, with several tan spots of a reddish tone to demonstrate rust, and I want them to be able to walk in the water, but very slowly, and for their weight and the fact that they are made of iron, sink into deep water, and take no damage when their breath runs out, but they have no breath. increase the resistance of this golem to potions of poison and instant damage, explosions of dynamite, creepers, crystals of the end, among others, the damage of lava and fire must also be reduced in it, however, a pickaxe should do as much damage as a sword , or even more, but only in golems. I want iron items to recover the life of the golem, like nuggets, bars, iron blocks, but with a certain inequality, iron nuggets would recover less of their life, iron bars a little more, and a block would recover a quarter of your life, as they need four blocks to be formed. The drop of the iron golem is a flower and iron bars, when dying, dropping vines or yellow flowers would make sense, as it is in your look, putting a certain rarity to drop iron blocks would be good, a potion of strength very rare if die while you were in your moment of anger, your fury.
