Piñata
From PinataIsland.info, the Viva Piñata wiki
Piñatas start out living the sweet life filling up with candy and other treats. Once they reach maximum candiosity, piñatas are called to duty and dispatched via cannoñata from the island to delight fun-lovers everywhere... in the traditional piñata way (bashed open by bat-wielding revelers!)
Then they head back to Piñata Island to do it all over again!
There are over 60 Piñata species to raise and collect!
