The sequel to the 2016 film.
The film picks up some time after the end of the first with the birds and pigs still against one another. However, things change when the pigs find out there's a third island, a snow-covered place, whose leader, a purple bird named Zeta, has decided she wants a change of venue and targets the birds' and pigs' islands. Seeing this, King Mudbeard goes back to Bird Island and convinces Red to have the birds and the pigs team up together against this mutual enemy.
As before, this is a collaborative effort from Sony/Columbia Picturesnote and Rovio Entertainment, with Sony Pictures Imageworks once again handling animation. The film is due on August 14, 2019, coinciding with the 10th anniversary of the mobile game.
