I have quite a few snakes that I'm intending to get, like a dumeril's boa and a blood python, but my biggest snake goals are to have a couple pituophis and drymarchon species someday.
A false water cobra and pied mussurana are more unlikely to happen, especially the mussurana, but still on a hypothetical list for if I get my drymarchon and then feel like I need yet another challenge.
