First u have to go to route 116 right of rustburto or petalburg forest.(i got mine at route 116). first of all after u get a nincada and evolve it to lvl.20.(bug pokemon are so easy to evolve give it exp. share and booooom ur done at lvl 19 go to pokemon center and make sure u have 5 spaces in your pokeball area stuff i mean like have 5 pokemon with u or less and your nincada some people say u have to catch it on a pokeball !no.! so after you get to 20 it'll evolve and it turns into ninjaskand learns like 3 moves yaaa. then after it does everything look at your pokemon and u see shedinja in that empty space so if u have any trouble dont be shy to ask ( P.S.) shedinja is level 20 but only has 1 hp lol sorry but thats it is so thanks please rate be good. :P
