Hmm sounds interesting. And crazy... hence your name. But anyhoo bug pokemon wise there isn't much that spring off the top of my head that are pure bug and all. Except for pincer but I don't have leaf, i have fire. But I'm not starting a new game on that so I may as well brush the dust off the vba lol. Anyhoo apart from pincer what ones could actually harm the ghosts in the elite 4. And am i enticed to go through the game with just caterpie?
