Riolu is one of my favorite pokemons (and it's evolution too) however, i don't have it registered in my pokedex so i can't get one by trading (but tbh i hate trading, especially when we talk about this kind of pokemons) Digging a little more in the pokemon wiki, i've found a way to get a riolu, i have to go to the safari zone and place certain objects in the meadow zone but the problem is : I HAVE TO WAIT 70 DAYS, idk about you guys but i don't want to wait that much, searching a little more in the wiki and youtube i found that you don't have to wait 70 days, in a video in youtube about how to catch a riolu, on the comment sections, some people stated that they didn't wait that horrible amount of time, in fact they said that they just waited one day....
the question is: do you guys know what do to get riolu in a lesser period of time?
(sorry if i have some grammar errors)
