Emperor penguins are the tallest and heaviest of all penguin species. These flightless, Antarctican birds can dive as deep as 1,850 feet and remain underwater for up to twenty-two minutes. Each animal pair is packaged with an educational ID Card that contains a unique secret scratch code for product registration and reward redemption. “We reward collectors with real prizes if they collect the entire series,” Caboodle! Toys LLC Co-Founder Steve King told TDmonthly. Launch date: 2007.
