What the fuck is wrong with scientists in Pokemon? How can they know so much and so little at the same time? For pete's sakes, they've learned to resurrect pokemon from small samples of DNA, and they made Porygon, which can exist in both cyberspace and the real world. Pokeballs built out of nuts!
Yet, no one knows what a Tangela or Cloyster or Forretress look like. No one has seen a diglett or dugtrio. No one seems to know where eggs come from.

And so on.
