According to my search on this lovely treat, Wikipedia has informed me that "Viva Pinata is a life simulation game developed by Rare, for the Xbox 360 video game console. Although rumors of the title circulated among fans for some time, Viva Piñata was officially announced on March 15, 2006, and first released in November 2006. With a "general audiences" or "everyone" rating, the game provides bright, colorful visuals, intended to appeal to children and more casual gamers. The game received a positive reaction from game critics, despite its poor sales and pre-release advertising."
It gets better! "The game features a wide variety of piñata types (60 in total), in most cases inspired by real-world animals. Some of the animals are "piñatavores", and must eat other piñatas in order to become residents or reproduce. ]When such piñatas are visiting the garden, they can and will devour garden residents in order to satisfy their own residency requirements. However, once piñatas are residents, they will not eat each other unless instructed to do by the player, although fights can break out between residents who do not share the predator-prey relationship."
Thing is, I am not so sure it's a good idea to have evil pinata eating pinata's out there. Seems even more painful for them than us blindfoldedly hitting them.
But still, it keeps getting better. In promotion for this game it looks like the Mexico Six Flags assisted in a promotation even where they created their very own Worlds Largest Pinata.
But get this, there is a TV show too!! I am still searching for where I can view these episodes, but for the time being:
