LTTP Unused Sprite/Tile Topic

Hello, this is to help with document the unused sprites and tiles in Zelda 3's VRAM. We already know about the Pols voice enemy and the fireball near it as you can see on The Cutting Room Floor LTTP page, but I found some others that seem unused.
Firstly, a lot of these enemies and projectile seem unused. Is the sword+pendant, fireball projectile, and enemies used? I know the lynel head, dwarf, and stone tablet is used.

Secondly, is this pile of bones near biris and stalfo knight (ice palace enemies) used?

The pile of bones is when you attack the stalfos that drop from the ceiling before they throw their heads at you (Eastern Palace and Palace of Darkness).

Secondly, is this pile of bones near biris and stalfo knight (ice palace enemies) used?

Yes, broken special Stalfos if you hit him before he throws his head, which then flies at you and can not be defeated.

This doesn't seem to happen even if I use sword beams, fire rod, somaria broken block fires, boomerang, or hookshot. Does anyone have video proof?

You need to hit them with a regular sword before the heads start to fly.
Of course this is an unique event, which will only happen when you open the big chest. So it can not be done after the chest is opened. Since this is a separate sprite, not the Stalfos sprite.

Thank you. Perhaps the ones in Dark Palace don't do that? That's the ones I tried. Also, here is some more stuff that seems unused; stuff I know is used in gold palette, and stuff that could be unused in green palette. I know the meat is unused.
