Okay, I just did a quick search. Look at this one! It's not a corn snake, but it looks pretty similar to your guy.. with the webbing in between the head and all.

And this one was found by a farmer.. so it actaully survived in the wild.

Name it Medusa lol
That is amazing. I am glad it is doing well so far. A two-headed ball python was born this year too. As far as I know it is still doing well and eating.
That IS interesting, huh? Do they have "similar" snakes in Spain? A lost pet??? A stolen pet??? LOL.Inrestingly enough to find a two headed cali King in Spain though.. Thats rare...
Best of luck, but statistically most 2 headed snakes die within a few months. There was that one at the San Diego zoo that lived for something like 15 years though. Good luck!
