Nickelodeon will celebrate "Dora the Explorer's" 10th anniversary with a range of pro-social and educational initiatives.

Its "Beyond the Backpack" campaign stars Salma Hayek Pinault in a public service announcement alongside Dora to promote school readiness for preschoolers.

An auction of limited-edition Dora backpacks, with designs by celebrities including Hayek Pinault, John Leguizamo, Slash and Shakira, will be auctioned off in countries including the United States, France, the UK, Mexico, Canada, Spain, The Netherlands, Greece, Australia, New Zealand and Israel. One hundred percent of the U.S. proceeds will benefit the Children's Defense Fund. One hundred percent of international proceeds will go toward childhood education in each respective country.

A dedicated website (www.dorabeyondthebackpack.com), with downloadable toolkits focused on local community activities across the country, will be available for parents and educators this April.

Other initiatives include: four prime-time TV specials, an original documentary produced by Brett Morgen (The Kid Stays in the Picture) and new online content for preschoolers and their parents.

Nick is also partnering with The Children's Defense Fund and National Parents Teachers Association for the multi-year, multi-platform program that champions overall school readiness for preschoolers.
