Instructions
Raise your gardener skill to level 38. Roario only appears to gardeners at level 38 or higher.
Increase the value of your garden to 50,000 chocolate coins. Breed valuable Pinatas to quickly meet this requirement. Plant seeds from valuable trees and plants, such as birds of paradise or gem trees.
Plant 80 square pinometers of long grass. Plant one gooseberry and one blackberry bush in the garden. This attracts Doenuts.
Feed five Doenuts six gooseberries and blackberries each to make them residents in the garden.
Purchase five Ponockies from the Pinata Pet Shop in town. Give them each one blackberry and one daisy. The Ponockies transform into Zumbugs.
Wait for Roario to visit your garden. When Roario eats two of the Zumbugs and two of the Doenuts, he becomes a resident.
