Instructions
Fight and defeat monsters that are level 20 or higher. All monsters have the ability to drop a pet egg after death, except for monsters below level 20.
Purchase eggs from some NPCs (non-player characters) for a modest fee (usually around 10,000 Penya).
Purchase a pet from the cash shop. While this might seem to defeat the purpose of obtaining an egg and raising your own pet, you will save a lot of time not having to feed your egg if you purchase a pet directly from the cash shop.
