I think the error was on our behalf, the tank with them in was next to the cornsnakes and they had a few different morphs next to each other and then 'Royal' on the end. We assumed it was a 'royal cornsnake' but alas it was a royal python. Like I said, I don't know much about snakes (but I'm here to learn!) it's my boyfriend who's the enthusiast, but even then I don't think he knows much about morphs and stuff.

Also, thank you so much for that sheet BPGator, it's extremely helpful
