Ghastling & Happy Ghast Improvements

Im aware its not available in the game yet, and i know its not the final product.

anyways heres some improvements to the awesome mob

Ghastling - A way to prevent growth since the first phase of the mob is really cute.

Happy Ghast - A way to set home point, so it doesnt wander too far from there, A way to upgrade it, such as giving him a heart of the sea, since its water related and all.

Upgrades - boost the health, ghasts die WAY to easily, it needs this, slightly boost the speed, if its meant for exploring then it needs to be atleast a bit faster than sprinting. A way to use it to attack, attacking with a bow will be probably inconvenient, so it would be nice if it could shoot stuff like the normal ghast, i think it would be awesome if he could shoot waterballs, it would make a ton of sense, and to make it balanced, you could make a way to recharge it with snowballs, just so you can play with the damage a little bit, and make it work a bit like a throwing water potion, if it hits the ground, it wouldn't place water, but rather just a water effect that dissappears after a while.

I think that making the ghast shoot fireballs would be inconvenient since it could burn down builds, so i think make it shoot waterballs would work and not ruin anything.

Thats my idea, i think it would make the happy ghast an even greater addition to minecraft.
