I'm not really sure, not very concerned either. Once my boy found out he could get a snake we would look at bhbs website. He went back and forth between a couple but finally decided on the ghost. I do know there are variations of the ghost so I'm not sure what Mario is exactly. I'm saving my coin for a super Lori ball. Coolest snake ever. Almost has a purple hue to it. But not cheap. Anyway can't stress enough how great Bhb was. I felt like I has hanging with old friends. Never felt stupid asking questions. They love to share their knowledge. Totally amazing with the kids. My six year old would point to tub after tub and Brian would take each one out (although a few he said "that one is a bit sketchy, lets find a new one.") if you are ever looking for a new snake I recommend BHB!
