Smiling Wither

About
This mob is the smiling version of the regular Wither. It has a 35% chance of spawning when you spawn a regular wither. It has 300 health, and the same drops as a normal wither. It is a neutral mob. If you attack it, then the wither will become a regular wither and will attack you. But, you can tame this mob with Wither Skeleton Bones. When tamed, this mob's health will fall to 250. Although, with this health drop, it does 5 hearts of damage plus the wither effect, instead of the regular damage.
