At first glance, the creatures that inhabit Viva Piñata are adorable, effervescent little things. They've got googly eyes, their "fur" is made out of papier-mâché, and they hop around doing their little dances. Your heart just oozes because it's all so damn cute. But then, realization slowly creeps in--you're now the reluctant owner of a murder garden for hellbeasts.
In order to feed your piñatas and make them stronger, you need to give them candy, which explodes out of these party favors when they die. It doesn't matter if it's another species or one of their own--they'll munch on the sugar-coated remains happily either way. Also, piñatas can breed to increase their population, but they don't care if their mate is a relative close enough to keep their family tree from forking. And when all is said and done, you're ultimately selling off these pitiful creatures, sending them out into the world to be beaten to death. For profit. Cannibalism, inbreeding, dealing with whatever the hell Fanny Franker is--it's all in a day's work as a piñata rancher.
