Of course it has to be in Trozei 2, which I assume no one really cares about, but still. Here's a bit of trivia for you: aside from Happiny and Chansey's Healer, only one NFE has a special ability. And it's a gen 1 mono-Electric type.
AND IT'S NOT PIKACHU. No, it's Voltorb. VOLTORB of all things is the sole NFE with a special ability that's not Healer. Talk about a random pick. But hey, as long as it's not freaking Pikachu again, I don't mind.
