One day, Mumble discovers he is able to tap dance before encountering a group of hostile skua, with a leader who is tagged with a yellow band, which he says is from an alien abduction. Mumble narrowly escapes the hungry birds by falling into a crevice. Now a young adult, Mumble is frequently ridiculed by the elders and their leader Noah. After escaping from a leopard seal attack, Mumble befriends five Adelie penguins named Ramón, Nestor, Lombardo, Rinaldo and Raul, known collectively as “the Amigos”, who embrace Mumble’s dance moves and assimilate him into their group. After seeing a hidden human excavator in an avalanche, they opt to ask Lovelace, a rockhopper penguin, about its origin.
