Common Sense Media March 26, 2012 at 5:23pm Parents need to know that Pocoyo World is a virtual world that includes avatar customization, games, videos, and other activities based on the Pocoyo ("little me" in Spanish) animation series, seen in more than 100 countries. You need to be 18 to register, so parents should fill out the online form. (Also, take note: When you sign up, you'll be automatically registered to receive a regular newsletter from the site.) Registration is free. For $3.90 a month, kids can join the world's premium club, which they'll need to do to buy certain costumes, toys, and other special avatar accessories -- but there's plenty to do without a paid subscription. You'll need to start at the main Pocoyo.com site to get to the virtual world; parents need to know that the main site has links to YouTube, Facebook, and Twitter. Although the virtual world is simple enough for young children to navigate, parents should explore the site with their kids, and not leave them unattended.
