Instructions
Find wild Pokemon by wondering through various areas in the game. You can find Pokemon in caves, water, tall grass and even trees. When you walk in any of the aforementioned areas, wild Pokemon will attack you at random.
Battle wild Pokemon using Pokemon that you have previously captured. Your attacks will drain the wild Pokemon's health points which weakens them for capture. When their health bar is blinking red, you have the best chance at catching them.
Throw a Pokeball from your item list to attempt to capture the creature. The Pokemon will disappear into the ball and will be caught if you are lucky. In some instances, even if the Pokemon is weak, it may escape the Pokeball and battle will continue.
Paralyze the wild Pokemon during your battle or put it to sleep if you can. This will make difficult Pokemon easier to catch.
