The Crimson Eye

The crimson eye is a very rare, flying mob that has the appearance of an a floating eye ball with tentacle-like legs beneath. Like a demon eye from terraria. It is extremely territorial and can be found around the edges of crimson forests. By itself, it doesn't do much, but when a player is spotted it comes a little closer and activates its "raging pulse" which agrivates all the piglins and hoglins in a radius to find and attack you. This is quite a difficult mob which is why it is very rare but when it attacks, it stays still and glares at you. Once it has started this, it locks into place and follows you at a distance. This means you can easily kill it once it is focused on you, all you need is a bow or to get close enough with a melee weapon. Once defeated, it drops quite a bit of xp, 10 rotten flesh and the "Cured Crimson Eye" which is a unique drop. This item is a copy of the crimson eye's eye and it is a bit like a compass except, the closer you are to looking at a nether fortress, the more the eye tenses and looks angrier. This can be used to find nether fortress. This mob would have about 7-8 hearts of health and move quite slow.

Here is an image which also shows my other mob idea from another post i will link here:
