Crystalline Golem

This golem idea is uniquely different from the current golems, both because it is designed for the nether and because it is not humanoid. This golem would be created by placing a head block on a crystalline body, both of which would be obtainable in the nether. I am not sure what the head block would be made from, but the body would be made from either quartz blocks or some other kind of crystal found in the nether. The golem would have many crystalline legs underneath a crystal head, and would be able to move like a spider. It would not deal as much damage as an iron golem, but would be able to reach places that an iron golem couldn’t. They could also spawn as hostile or neutral mobs in the biomes where the ore used to build them is found.
