Watch | Penguins visit New York’s World Trade Center

It was a march these two penguins won't soon forget. Perched 102 floors above New York City, Betty and Vern waddled to the edge at One World Trade Center, a view far from their native southern African waters. The two endangered African penguins got to take in a 360 degree view... and entertain children as part of the New York landmark's “Kids Day” holiday celebrations.
