Pokemon in Hidden Grotto?
I've been to all the Hidden Grottos numerous times, and the only Pokemon I've ever seen in one was the Minccino in the Route 5 Hidden Grotto. I visit them every day, and I can only find items and Foongus/Amoongus (disguised as Pokeballs). Is there a reason for this? Do I need to do something to get them?
I'm playing White 2, I've been in the Hall of Fame many times, have most metals, and completed Unova Pokedex.
