[Both explanations give him pause - he didn't really know what a ghost was until he came here, and he still mostly thinks of them as a Pokemon type. But weirdly enough - because he's aware that humans cannot go to StarClan when they die - it is nice to hear that they turn into something instead of just disappearing.]

I don't know either - but I can ask one of my friends when we get back to the city. Emporio knows everything.

[Granted, Firepaw frequently overestimates how much Emporio knows... but it's usually a safe assumption that Emporio will know something relevant.]

I don't know all of the Pokemon species, and you're something I haven't seen before. But we can ask Ingo or Emmet what you are - or one of the guild leaders. They'll know if you can learn anything that will work against Digletts, too... but you're probably better off not coming back to this part of the forest. It's really dangerous here.
