Hatchlings

The Hatchlings are baby birds making their debut in The Angry Birds Movie. They were first unveiled in a holiday video of them singing "Deck the Halls" very badly. The children voicing the Hatchlings were asked to sing "Deck the Halls", but apparently none of them knew the lyrics.

The Hatchlings made another appearance in a Easter video in which they discuss the Easter Bunny.

It is unknown if they will be what hatches from the Eggs.
