Erik, son of the penguins Mumble and Gloria, is reluctant to try dancing as most of the penguins in Emperor-Land do. His first attempt at dancing ends with him being stuck in the ice headfirst and peeing in embarrasment in front of everyone, making him subjected to ridicule just like his father had been. Erik and his two best friends, Bodicea and Atticus, follow Ramon to Adélie-Land and find that Adélie-Land has been ruled by a God-like "penguin" named Sven. Sven is the only one of his kind in Emperor Land, he survived the loss of his native fishing grounds (evidently ruined by a warming climate) by his "miraculous" ability to fly (from his appearance and accent, the audience, but not the penguins, can realise that Sven is really a puffin). Erik instantly becomes enamoured with Sven, who takes a liking to him. Sven and Lovelace the rockhopper penguin tell the others that they were saved by humans. The two eventually flee and end up on Antarctica, where Sven performs his first miracle by revealing moss to the local penguins. Sven uses his power of "Sven Think" to help Ramon find a mate. Ramon instantly falls in love with Carmen, another Adélie penguin who is uninterested. Mumble follows the chicks' footprints to Adélie-Land and orders them to return to Emperor-Land, but they refuse. Sven sends Erik back to Emperor-Land with Mumble.
