Armor, more health and dash movement for happy ghasts

I think in order for happy ghasts to have even more uses, such as for pvp, it may be beneficial to give them more health than an ordinary ghast as well as allow them armor to keep them more protected. Furthermore, a dash movement thing would help avoid potential arrows, and act as a way of dodging since the ghasts normally move slower than an elytra. Also, to make it not fall into the pit trap horses have in pvp, make happy ghasts immune to fire damage (probably in lore cause they’re filled with water), and maybe even poison damage. It would be really nice for these guys to mess with the pvp meta, especially if they’re implemented well.
