Instructions
Head over to Monstro City via the map. The city is located in the middle of the map. Click on the city icon to travel there. Click on the Monstro Seeds Cart once you arrive in the city.
Buy three seeds that will allow you to find and catch two Moshling pets at once. Those three seeds are: love berry, magic beans and dragon fruit.
Plant the seeds in your Moshling Garden and allow them to become fully grown. Once this happens, two Moshlings will appear in your garden.
