It looks to me like a very cool normal . But again like everyone said only time and breeding will tell for sure. I highly doubt that any pet store would sell a vanilla. By the time they get there they've already been through so many hands and the babies have been picked through so many times it's extremely unlikely that any morphs would get through. But you never know! Crazier things have happened Good luck with him and if he doesn't prove to be a vanilla you've still got a great looking snake
