My wife thinks that this picture should go on the site as although Helena isn't wearing a fur bikini she seems to be wearing something made of some sort of tropical vegatation. I think that this gives enough of a prehistoric effect and there should be some beach cavegirls, anyway. By the sea is a good place for caves so it would have been a good place for cavegirls!
Anyway, I've always liked Helena so I don't need much of an excuse to put her in. Helena herself would probably get an 8/10 but she isn't wearing a fur bikini hence:
Cavegirl rating: 7/10
