Zombie Giant Rework

The Zombie Giant is the most forgotten mob, isn't it? I'd like this mob to have its own functionality. For example: Warden lives in an ancient city, zombie giant would live in a swamp. When you kill this mob, it will drop something interesting, besides flesh. Item what you want, idk what item can drop from zombie giant. It's not stopped by water as long as it's less than 5 blocks deep. It can jump 5-6 blocks high. He is slower than a regular zombie and burns in the sun longer than regular zombie. Its health is 300, but it can be made lower. It's like a Warden in melee combat, but weaker. I want to see zombie giant in normal game. And give it a little redesign.
