Warden drop (Caves and cliffs)

Warden is a scary mob for 1.18. No one knows what it will drop. Here is my idea. What if the warden drops its head . And players could wear it. And maybe you can see any mob/player even invisible but only highlighted or glowing ,even through walls or underground. Although there is a disadvantage, you will get blindness as long as your wearing the warden head.
