Getting started
To breed any Pokémon, a ranch block is required.
After placing down a ranch block, up to six Pokémon from the player's PC (not the player's party) can be put into the ranch block, where they will begin to wander within a 9×9 block area around the ranch block. If, within these six Pokémon, there is at least one pair of Pokémon that are compatible for breeding, the breeding process will begin. Multiple breeding processes can occur concurrently with the ranch block if there are multiple pairs of compatible Pokémon.
