He walks with his short legs, making a sound like 'PoPoPo...' That's why his name is Popo (Not onion). With him, you will look much cuter.

Our cute mailman Apollo will deliver a Popo seed into your Collections in all servers. You can recall him with the seed whenever you want. You cannot recall two of them at the same time. The item will not be lost even if you delete your character. It might take more than 5 mins to receive the item, depending on the Steam server status.
