I only know that in Platinum If you swim in the lake beside the Battle Frontier and go upwards, You'll Reach Stark Mountain where Heatran will be available and that you can get Cresselia somehow but I don't know any Secret ones in Diamond unless you include ones that you need the AR for(Darkrai, Shaymin, Arceus ETC.) and ones that you need the old games for(Regis) P.S. I think you can still get Heatran and Cresselia in Diamond Though.
You can only get the secret key in Pokemon Platinum
If you are referring to secret bases, then a WiFi connection is needed.
You can't rotate items. They stay in the direction you get them in.
Pokemon league champion Cynthia will give it to you when you run into her at lake valor(near pastoria and sunyshore)
yes you can if you can't do under ground you have to get an explorer kit. but when you do you have to get an digger drill. and pick aplace to have your secret base. :)
There is no secret Pokemon in diamond and pearl but there are ways to get Pokemon you cant catch on diamond and pearl. For example manaphy. You must clear the manaphy mission on Pokemon ranger. Goodluck with the game!
No it is not
You can only get the secret key in Pokemon Platinum
Pokemon Diamond Pearl and Platinum are games in the Pokemon series. There is no secret store in Pokemon Pearl version.
yea......there is three
arceus
in Pokemon diamond you can only use it in battle since your cave/house/thing is underground
No there is no secret store I know that for I have beaten the elite four 20 times and have searched every corner of Pokemon diamond's world.
Game stop
no:) Eer... Right. You -could- get Secret Power in Pokemon Diamond, but I don't recall where I've obtained it. And I think you use it in the Underground if you have Wi-Fi. You find it in Amity Square. :]
It is probably a cheat
It's a Pokemon event. you have to wait. when will this event take place.
