I guess my question to that is, how does it make sense for something Electric to evolve into three completely different types? I mean it's definitely not impossible (because Game Freak does what it wants), but logically that just seems...out there. I mean, if the monkeys just evolved by level up naturally instead of stones, you could theoretically state that using whatever stone would evolve it into Pansear/sage/pour from like a Normal type pre-evolution. But I guess I don't see them having something. Who knows though!
