Instructions
Load your previously saved game of "Viva Pinata: Pocket Paradise."
Play through the game until you reach Level 6. Level 6 is the minimum required to attract Horstachio to your garden.
Expand your garden as you level up. If you frequently expand your garden, you will have at least 500 pinometers of grass in your garden, which Horstachio needs to visit.
Purchase a Ponocky from Gretchen and place it anywhere in your garden. This meets the minimum requirement to have Horstachio visit your garden.
Give Horstachio eight apples to eat. After the eighth apple, Horstachio will change his status from "Visitor" to "Resident" and this lets you have a horse in your garden.
