I know alot of people have him so is he in Pokemon Mansion cause its in that book so then he`s in your pokdex so just please help!!!!!!!!!
I assume you mean Phanpy and Manaphy?
Phanpy is acually at Canyon Entrance and Seavault Canyon.
Manaphy is an event
>Received from Pokémon Ranger from Fiore, Almia, or Oblivia (Egg) -Bulbepedia
You get manaphy fro an event, and if you breed it with a ditto, you get a phoine.
Phanpy you can find at seavault canyon and canyon entrance
