The Pebble and the Penguin (remake)-opening

Narrator [V.O.]: There is a charming tradition observed by the Adelie penguins: Once a year during the mating season, all the male birds gather on the Antartic beaches, and there, each selects an extraordinary pebble. With pebble in hand, each male presents his precious gift to the lady he most desires! If she accepts it, they mate for life!
