I'm going to catch a Drilbur, but when I step into a dustcloud, I get an item? It's frustrating, because I thought that, I would encounter a Drilbur! And I doesn't use repels, before I see a dustcloud.
Yes.sometimes items do occur.Its a random possiblty for an item to come.Dust clouds are a phenomenon that only occur in caves. It may reveal held items, evolutionary stones, or wild Onix, Steelix, Drilbur and Excadrill.But getting a drillbur is very easy.So keep trying and dont give up.
