Looks to be a chalice of some sort.

Im pretty sure it's a chalice. Where'd you get it from. That may help in ID. Kinda looks like a TSA Luigi chalice. I'm probably wrong tho lol

An obscure LFS that isn’t local, and mailed me some coral I ordered

Looking online it could be this

But its a generic name “ultra green orange eye” lol
