The Crawling Hand or The Crawling Claw

Crawling claws are undead hand-looking hostile mobs that can climb to the top faster than spiders and get out of tiny cavities, they can jump from the up towards you and they get in your face, when you can't see anything and be on your face for 15 seconds and you can’t hit a crawling claw, but if you hit it before it jumps then use a shield because it works to prevent them from jumping on your face, from below they can also attack you.

Crawling claws are also not easy to kill, they have a petrified terrefying meelee attack animation, they are able to breathe underwater even at the very bottom and can bite you poisoning to death.

Crawling claws spawn deepest dark places/caves, and if your house is too dark they spawn rarely there maybe, cause they thrive in really dark small cramped places.

If you kill crawling claw then it will drop 0-2 rotten flesh and 0-2 sharp claw (the sharp claw item look so scary too.

You need craft necklace first, if you want to make the necklace more scarier, then carft 1 necklace and 5 sharp calw, then you get a claw necklace, you can put it around your neck.

Crawling claw mob or claw necklace will scare some humanoid mobs like villagers, wandering traders, illagers, pillagers, witches and piglins, so these beings dare not attack you, I dont know why cause they are scary and disgusting looking mobs.

The claw necklace can break if you wear it too much. (Crawling claws burn in daytime maybe.
