Breeding is the method of choosing two of your Pokémon to send to the local region's Day Care in the hopes that the pair will produce an Egg. This is a useful technique to raise Pokémon with unusual attributes, such as elevated Attack, Defense, Speed, etc. compared to members of the same species on a similar level. Pokémon that are hatched from Eggs can have access to stronger attacks earlier than normal, such as learning a parent's TM or HM move. Some Pokémon, like Pichu, can learn a move the parents would never learn, such as Volt Tackle if one of the parents are holding a special item, such as the Light Ball in Pichu's case.
