Yeti

The yeti is a rare mob that spawns in tundra biomes.If approched,will run away.Upon chasing it,it will attack you,give you blindness,and dissapear.If you kill one,it will drop either snowballs,or rarely,it will drop a sacred gem.Sacred gems are unpredictable.When you right click the ground with it,it will either bring chaos,like making it rain arrows,or goodness,like giving you 50 diamonds.Yetis have 50 h.p.,and do 9 hearts of damage.If the yeti gets away,you will find a trail of footprints.Follow them to find a yeti cave,which have chests with random stuff in them,and rarely the yeti will be in there.The sacred gem can also be used to make the corrupted orb,by putting a sacred gem in the middle of the crafting table,then putting eyes of ender around it.A corruted orb,when placed down,will bring the ultimate chaos,like bringing an endless,ghast apocalypse in enternal night,or the ultimate prize,giving you a mansion with 50 tamed wolves and ocelots,and an endless amount of food,with 20 Iron golems standing guard.
