If you are going to play a Pokemon game, you must capture Pokemon to proceed in the game.
You catch them with round objects called Poke Balls. They can be found hidden in the
ground, visible on the ground, bought in Pokemarts, a prize in the Golden Rod Department
Store, found in the grass on the Poke Walker, and many other places. Here is a list of
