YIKES.... that snake has been through hell and back!!! It doesn't looks like a car hit, the affected area should be smashed flat if that were the case... the back end of the snake looks severely kinked and as for the prolapse.. man i don't know!!! It does not look good at all Kyle

You can also try putting sugar on the prolapse and very gently try to re-insert it if it will go? Or is it swollen and infected to the point that it won't go back in?
