Where do you see number 152 Sinnoh pokedex on Pokemon platinum?

Answer 1

You go to eterna forest and if you know where the abandoned mansion is in the forest you go in there and then (before you go in you might want to use a repel) so once your in go up the left stair case and then go to the door in the middle of the room once you have done that go left again and the door 8 feet away from where you entered left and once your in there, there is a tv but it has to be past 8:00 at night or it wont work anyway once your in front of the tv you press a and then #152 will come out of the tv but remember it must be past 8:00 at night!!
