As a brief promo by a Sea World Animal Ambassador tells us before the movie begins, male penguins really do present pebbles to the females during a courtship that will result in a lifetime match. This post-Thumbelina Don Bluth/Barry Manilow effort gives us Hubie, a nerdy penguin whose love for the beautiful Marina, remarkably, is returned. Alas, before he can present her with a fine stone, his evil--and strangely buff--rival throws him into the swirling sea. Epic adventures and a comical sidekick result. Leopard seals and killer whales threaten, but kids will be entertained rather than frightened by this harmless, if less-than-brilliant movie. --Kimberly Heinrichs
