When is the best time to look for Ditto? (On Diamond) I know where Ditto is and that you have to use the Poke Radar but i can't find one, so i was just wondering if it only appears at a certain time (like drifloon only appears on Friday).
go to the pokemon mansion and keep talking to the owner and he will say that he saw a certain pokemon in the garden. wait until he says he saw a ditto and go out and search for it.
