I love MarcoPolo Ocean, and so do my kids! We happened upon it when it was free last year, before Cynthia had even reviewed it to make it a Top Pick. You should definitely check out her great review, because this app is one to have on your device. Kids can learn about oceans and ocean animals, all while playing and exploring with this app. My daughter's class is just finishing a unit on the ocean, and I know she'll be happy to rediscover this app. Get it now, while it's FREE for a limited time!
