Hi. Is it worth trying to RNG for a Hidden Grotto Ditto in Giant Chasm even if I haven't played through the entire game yet? I'm just past the point where you fight White Kyurem / Ghetsis (no spoilers pls), haven't done anything else. I have not been in any Hidden Grotto so far, but the problem I'm seeing is that there are some on the map that I cannot visit yet - I'm assuming they're full since I'm already pretty far into the story (walked a lot of steps), but I don't know for certain. Any ideas?
