Screecher- the lost soul haunting the Minecraft world

The Screecher is a Mob that I originally wanted to add into a mob I was making. I really liked the idea of this mob. It just felt Minecrafty. That’s why I’m making this post. I designed it off of a ghost and it would have been found in an ice cave (obviously you have to find a different place for it to spawn since the ice caves are only from my mod) the Screecher would hover around similar to the way that blazes do. He would also have a screeching attack where he shoots out a sound wave and deals a small amount of damage and gives the players a new effect called frightening. What does frightening do? It causes the player to shiver in fear and make the screen blurry. It would also make the players controls slightly inaccurate. I know u are probably not intending on adding another cave biome but I’m just saying that an ice cave would be really cool. Something about a cave that feels gloomy and all blue with ghosts flying around just sounds like it would fit in with the game very well. (I have a few sketches I made of the mob and some pixel art I just can’t figure out how to post them on here)
