Hmmmm, nice snake, though if it's a yearling it's probably the biggest I've ever seen.

I don't think I'd call it a banana, those really need to be 90% yellow in my opinion.

I do think it's aztec though, or dang close which is a much more uncommon morph at the moment.

No matter the pattern though, they are fantastic snakes.

Oh, and they do tend towards loose poops.
