Protective shell for shulkers.

Mojang could add this: The shell of the shulker can protect it from taking damage. When the shulker cover itself with its shell the player can only damage the shell which has around 80 to 110 hp. When the shell opens the player can damage it normally. When the shell has 0 hp it breaks but regenerates over time. Hopefully Mojang adds this. By Prateek Morusupalli.
