[Connor pulls a chocolate bar out of his pocket, but rather than start eating it he breaks off a piece and hands it to the Raichu that immediately appeared the moment it heard the wrapper crinkle. Buntz sits himself on Connor's shoulder, looking at Drifter as he nibbles the chocolate.]

If you're looking to collect snake Pokemon perhaps an Onix would be good too? It's known as the "rock snake" Pokemon. I have a Steelix, the evolved form. They're very good in battle, and given their huge size they make good travel Pokemon too.
