Looks like Doof-a-Palooza is back, bigger than ever! The food-backwards team behind “Doof,” the new public television cooking show (coming in 2009) for kids, is hosting another foodie family extravaganza at Google Headquarters in Mountain View July 12 from 11 a.m. to 3 p.m. And it looks even more spectacular than the last one, which drew more than a thousand enthusiastic kids and parents. There’s a kitchen sink cook-off for kids with Bay Cafe’s Joey Altman, pizza-making lessons, foodie treasure hunts, and scores of great cooking-related activities for kids. Tickets are $12-$20 (kids 5 and under are free.)
