They are the alphabet :)
The Solaceon Ruins.
no, these Pokemon are unknown in Pokemon platinum
That is unknown.
you can get seals with the unknows
In Diamond it is in the ruins with the Unknown, I am not sure about Platinum though.
It's currently unknown which countries Pokemon Platinum is gonna be launched anywhere else, other than Japan.
If you mean to say "How do you get the description of the pokemon in Pokemon Platinum?" then I would say that you have to catch them in order to see their description. If that is not what you mean to say then I am confused and can not help you.
lightening bolt
1. On the game case it will say 'Pokemon Platinum'. Lost the game case? 2. On the game cartridge it will say 'Pokemon Platinum'. Has the sticker come off? 3. When it is inserted into a DS system, the game display should say 'Pokemon Platinum'.
I am sorry to say this but, you cant catch any of the Pokemon in platinum in ruby unless it is a hoenn Pokemon.
At the Solaceon Ruins in Solaceon Town, different rooms has specific Unknown in them. . . so its kind of HARD to get a specific Unknown. . .
You can find the M form of Unown in the Solaceon Ruins of Pokemon Platinum. This form of Unown appears in the dead-end rooms of the Ruins.
