Creaking Crawler

The creaking crawler is a new mob, sort of a combination of a creaking and a spider.

Creaking crawlers are 1.5 blocks tall, and they look like a giant orange eyeball held by pale oak wood with eight spider-like legs, but thinner and also made of pale oak.

They are twice as rare as creakings, and they spawn on the bottom of leaf blocks in pale gardens. Like their larger cousins, they have creaking hearts, are hostile and immune to all damage, and will freeze in place if a player is looking at them. Unlike creakings, crawlers will close their eyes as soon as they are within a player's fov, making them harder to spot. They can climb on walls and ceilings. Their method of attack is to climb directly above a player and fall on top of them, dealing heavy damage. They have no method of attack on the ground, so they'll then flee to the forest roof in the direction the player isn't looking.

I hope you like this idea! Vote if you do!

p. s. Also suggest item drops in the comments. If creakings don't have a drop, their crawler variant definitely needs one.
