To help promote the Xbox 360 game Viva Piñata, Microsoft is holding a family-friendly party this Saturday on the Santa Monica Pier in Los Angeles. The free event will take place from 11 a.m. to 3 p.m. and will include giveaways of Xbox 360 consoles, copies of Viva Piñata, and other piñata packages. Other activities include learning special Viva Piñata romance dances, photo opportunities with Hudson Horstachio, Fergy Fudgehog, and Paulie Pretztail, face painting, a free merry-go-round, and a 35-foot-tall Horstachio piñata. For more information, read the details over at Microsoft's Gamerscore blog. [UPDATE] The event will be hosted by Mario Lopez--better known as AC Slater from Saved by the Bell.
