March of the Penguins
Penguins had a resurgence as figures in pop culture in the mid-2000s thanks to films like "March of the Penguins", "Madagascar", "Happy Feet", and "Surf's Up". As an April Fools' Day joke, on April 1, 2008 the BBC released a short film of penguins in flight and migrating to the South American rainforest.
