The Mangler

So...What is the Mangler you may ask. This is a new hostile mobs that spawn in the Dark Oak Forest. Maybe it can be in a biome update. The Mangler Spawns at night. It is grey with crystal covering its legs. It is a mob that is upright but hunched down. He has a large horn on his head with a crystal. This crystal is an alternative to bookshelves during enchantments. The thing is with this mob is the fact it is insanely powerful for just a mob to find all over. Every night only one spawns and in the day it burns but the mob doesn't drop an item while burning. Now the attacks... You see it is called the mangler because it does 5 hearts of damage each attack and has 50 health but the attacks also give you slowness 2 for a minute almost like in mangled you up and ripped a body part off or you are badly damaged. Now to mention the crystals the Mangler drops... He drops 1 each time he dies and you need 20 in the place of lapis to get full enchantment level. Another thing with this mob id it can drop bones as it is a flashed creature with very brittle flesh and strong bones the flesh is not rotten though. The mob would be red with green eyes. The final thing I have to mention is the mob hates many other mobs specifically: Creepers,Zombies,Iron Golems,Spiders,Illagers,Vex's and although this mob doesn't attack they kill horses and sometimes wear leather boots.
