Agri Birds

Agri Birds was a fake game trailer was released on Rovio's YouTube account on April 1, 2015.

It was meant to be a role-playing farm game, with the player making their own dialogue choices. There was also a reference to the game Five Nights at Freddy's, with another gameplay element being surviving in an old farmhouse at night with The Blues attacking.

From the very unusual nature of the trailer, the dramatic change of characters, and the fact the trailer was released on April Fool's Day, this was revealed to be an April Fool's joke. (see Trivia for more information)
