A code to see Mew on the Pokemon Hall of Fame (sent it by Animoon256)
First, beat the Elite Four 12 times. Then, after you beat them the 12th time, go straight to a PokeCenter and look at the Pokemon League website. You will see a bunch of pictures of strange pokemon and other pokemon that are over level 100. Mew will be one of them. You can't use Mew or capture it, you just see it on the computer.
A code to capture Togepi (sent in by a reader)
You need the Itemfinder to actually start this code. Then, walk around Mt. Moon and use the Itemfinder on different areas. Do that 100 times. On the 100th time, it will say that the Itemfinder reacted and you will have found an egg. Keep walking around and eventually the egg will hatch and you'll have Togepi. Togepi is found near the exit of Mt.Moon.
Here is a code to get a pikablu (sent in by an anonymous reader)
You need a friend with the game and a link cable. You or your friend needs to capture a regular pikachu. Then, trade the pikachu 10 times between yourselves. On the 10th time, give the pikachu a water stone and it will evolve into Pikablu.
