Dancing Battle! Ludicolo!
Well, I gathered that this is NOT Brock's Lombre that evolves. It belongs to a trainer in the woods named Pancho, who trains his Ludicolo with his drums. Also, it's Corphish's turn in the spotlight. Ash battles this guy, wants to use Grovyle, but the paranoid Corphish insists that Ash let him battle Ludicolo instead.
Now... what I'm not sure about is: Is Corphish jealous and wants to evolve too? Or is Corphish just paranoid and thinking that Ash favors Grovyle cause of its stage, and wants to prove that he can battle just as well without evolving?
Well, maybe it's just me, but I'm pretty sure I heard "Heigani" and "Shinka" in the same sentence. I doubt it evolves either way though, because it's unlikely they'd give Ash a Dark type, especially Crawdaunt which could get you arrested. OMG HE HAS A CRAWDAUNT, HE'S FROM TEAM AQUA!
But actually, I don't think it was the Crawdaunt that got the guy suspicious back in "Stairway to Devon", but I think they gathered it from Mischief-maker + Crawdaunt = Team Aqua member. Everyone knows Ash is a good boy...
