Body Parts: Are these rare and where do they come from?

[Vesti]

Hi all.

I failed to find any solid information online, so asking here.

Does any of you know where the below items are from?
Body, Right Arm, Head, Head, Head and the one on the second row is also called Body.



These aren't from Players but look the same.

I suspect the lower one is a drop from some mobs but the upper ones I don't think spawn anymore. Does anyone have any information?

Thanks!

you can get these from different mobs as well, undead, ant lions ect.

you can also fish them up from SoS, but they have the tag recovered from a shipwreck

One of the Halloween trick or treat events had a trick that blew you up too. I collected alot during then.
