I’m with Jimmy. Looks like a triop to me, too. Maybe a little bigger than the one in this video, but otherwise seems nearly identical, given the
crappy quality of the video.

It’s clearly been coated in some kind of green goopy substance. You can see the puddle of the green goop underneath it and how when it raises its
tail, it leaves a bit of the goop on the surface. May be that some idiot coated in in green paint or something of that nature to make it look more “alien.”

Somebody else thought they looked like alien critters, but without the goop…
