there isn't one you go to the Pokemon mansion and behind mr.blackout or something there is a book you read it and then manaphy is in your pokedex
Pokemon number 151 is Manaphy - you can only see it by reading the book on the table of Mr. Backlot's room (far right door) in the Pokemon Mansion. Mew is, as far as I know, unobtainable apart from with an Action Replay in Platinum. I'm sure I can conjure one up though, so if you're that desperate for a Mew exchange friend codes and I'll send you one if it lets me.

In Pokemon platinum, the number 151 is Manaphy. You see him by going to the one mansion with the trophy Pokemon garden in it. In the room with the owner, you will see a book. Read the book to get him in your pokedex. Otherwise, you will need to have a Pokemon ranger event to get Manaphy.
You cant, but you can look at the book in the Pokemon mansion to see manaphy.
