Is the picture of your snake showing its natural colors or is the lighting not great in it? You just mention you think it might have jungle in it so I was wondering what it looked like. Do you have more pictures of it showing it fully? Belly too? Carpets get cross bred so much it is more likely then not to have some percentage of different subspecies in a subject now a days so it could be likely you have a coastal jungle cross. If it is a yellow coloring that makes you think that also remember jag is a coastal trait so it could just have some of that in there too.
