I don't want to sound like I'm kicking someone while they're down, but this is why doing your research is so important. As soon as the guy said Pastel x Pinstripe, you should have been late for the door. A Pastel x Pinstripe is a Lemonblast, and that first snake, while a beautiful Pastel, is not a Lemonblast.
But, at the end of the day, you have three females for your breeding project, and a lesson learned.
