Pokémon Platinum Version Easter eggs

Get Rotom
You will need HM 01 Cut to do this.First,wait until late at night,or you can just set your DS clock to about 11:00.Next,go to Eterna Forest and get near the exit,and there should be a tree you can cut if you go north.Cut the tree and enter the building.Start looking at all the rooms until you find one with a TV.Interact with it,and you'll say something like"Huh?There's a pokemon in the TV!"then it will ask if you want to thump the TV.Say yes and Rotom will come out and battle you.Rotom will be at level 20.Happy cheating!
