I wanted to catch a riolu and a shelgon about a couple of weeks ago.I put the objects, on serebii.net it said they need 70 days to appear but the result was Instantaneous. but now when I put objects to get a cacnea and lunatone they do not appear. why did riolu and shelgon appear Instantaneously while lunatone and cacnea do not?
It means that if you leave the objects for 70 days that the 2 pokemon will become naturally occuring. As for the other two, you are not lucky.....
