These are two mini-size polishes, Ulta N-Evergreen and Mod Polish Chupacabra:
here and here. The latter one says the collection was called Cryptid, and that does sound familiar. It also seems to imply a Halloween collection - because "crypt" right? but still not 100% sure about that.) I don't think either of these are likely to be available any more, in any case. I have Mod Lacquer on my indies page but it looks like that link doesn't go anywhere any more.
(Oh, and the cap of the Ulta polish looks so weird because it was sticky and I was so frustrated with it that I actually took some random older polish and polished the cap so it wouldn't be sticky any more. It doesn't look pretty but it helped.)
