That is too bad...he is cute.
Since it won't fix itself on its own and more then likely will end up getting infected is left alone you really only have 2 options that I can see.
1. Euthanize - I don't know how you do this with a snake humanily so if everyone else agrees someone with more experience can help.
2. Take him to the Vet for surgery to fix it.
Maybe someone with more experience will have another option![]()
