ORLANDO -- Before losing its sheen like an iceberg with a bad case of global warming, "Antarctica: Empire of the Penguin," the new attraction at SeaWorld Orlando, is an innovative how'd-they-do-it? dazzler. The centerpiece of the park's new tundric landscape, the spinny "dark" thriller pushes the boundaries of ride technology -- and keeps creative pace with those theme-park foes across Interstate 4.Well, for a while at least.Sure, SeaWorld has a bunch of rides, but it's mainly in the Shamu biz. Go for the fish; stay for the Kraken. And yet, "Empire of the Penguin" does two things that are decidedly Disney in vision. First off, as guests enter the fictional world of baby Puck the Gentoo penguin -- and escape 90-degree-plus Florida outside -- they are acclimated to increasingly cooler climes: 60 degrees, 40 degrees and finally 30 degrees, which allows the 250 real penguins, revealed at ride's end in an indoor habitat, to feel as if they never left the igloo.
