The 3rd one w/ the transparent green base is a clown, I don't see any crosthroughs here so the other 4 are clear clowns IMO

Pelt here, not only looks Pelt but I've never seen a Vitro w/ blowholes like that. Vitro had pretty tight quality control whereas blowholes are (I hate to say it) common on Pelts.
