Double bill of children's animated features. 'Happy Feet' (2006) tells the story of Mumble (voice of Elijah Wood), a young emperor penguin who struggles to perform the heartsong which is crucial to finding a life partner. He discovers that his talents lie in his feet, with his ability to tap dance like nothing the others have ever seen. Unfortunately in Antarctica his toe-tapping talent is deemed peculiar and poor Mumble is branded an outcast by the emperor elders and is even accused of causing the mysterious fish famine which is gripping the penguin community and threatening their way of life. Mumble decides to leave his family and goes on a journey to determine the real cause of the fish famine so he can prove his innocence. In 'Happy Feet 2' (2011) Mumble is dismayed to discover that his son Erik (Elizabeth Daily) cannot, or will not, dance. Instead, Erik idolises The Mighty Sven (Hank Azaria), a penguin who can fly. With no hope of competing with this charismatic new role model, Mumble gives up all hope of passing his passion onto his son. But when their world comes under threat from powerful external forces, Erik realises that his father is a true hero after all.
