Yes you do unless you want to do a lot of trading instead.
You have to complete your pokedex the oak gives you a call
I did the same thing and the only way that I found is to use the AR cheats to completely fill both the johto AND the national pokedex I'm not sure what it does if you just fill national but I would imagine it glitches.
you get your legendery pokedex!!!! you get your legendery pokedex!!!! you get your legendery pokedex!!!!
Cheats or trading or dual slot baby. Cheats or trading or dual slot baby. Cheats or trading or dual slot baby.
u hav to find all of the Pokemon in the national pokedex
Munchlax is found via honey trees but I have never caught him, he's rare. Type in 'pokemon pokedex' on Google.
You have see to many different pokemons. Then you will fill it (you have to every Pokemon to get national pokedex).
just use the Pokemon global trading system. if you have platinum pearl or diamond it is in jubelife city. and if you have heartgold or soulsilver it will be in goldenrod city.
