In general this is going to be totally dependent on the location your son is at. However, if he checks with his school league they'll be able to direct him to any ongoing camps.
Do you mean walk through walls cheat?
You need action replay to do this cheat but it is only on Pokemon pearl
After you get the HM Rock Climb, and a Pokemon knows it, you can approach a rocky wall, press A, and you will scale the wall.
You have to get an action replay, or hack the game itself. To use it, you just walk through a wall.
well you don't but you can catch it you need the walktrogh wall cheat and the always catch 100 % cheat on action replay and PS first do the elte 4
To find heart scales on Pokemon diamond/pearl you need the explorer kit to go underground. once you are underground look for cracks inthe wall, and eventully you will find a heart scale in the cracks.
go to cresselia island and use walk thru wall cheat and walk right until see a island
Rock Climb isn't a move in the game. It wasn't introduced until the 4th generation games (Diamond/Pearl/Platinum).
In both games, go to Mt Cornet near the first gym, use rock climb on one wall then go find Dialga in Diamond or Palkia in Pearl.
I don't no yet
You don't. its for the plot. Nothing more

You need to have a walkthrough wall cheat and skip getting the starter pokemon.
