Mob Menu

I'm proposing a menu that you can deselect specific mobs for these reasons:

1. I know many children who have to go into peaceful mode specifically because of the undead mobs. 

2. peaceful can get boring

3. If Mojang could at least add a setting to disable the undead mobs (any kind of zombie, skeletons, and drowned) that would be really awesome.

The purpose for this is so that kids I know can still play on easy/normal/hard mode without undead mobs.

Thank you!!!
