[Kaderin Triste]

I don't guarantee it's true, but one pogo list (because I had too look up the second gen that are in game since I'm not super familiar with gen 2 and up) said that the regional exclusives could be obtained through eggs.

And honestly, anything on that list that I already have at least the first evolution of, I can walk to get the others. It'll kidt take forever. But I only need 2 more Kabuto candies and then I can swap buddies for the next one. Probably whatever one needs the fewest candies first.
