Agri Birds

Agri Birds was a canceled farming and visual novel game created by Rovio. Released as a joke trailer in April Fools 2015, a former Rovio employee confirmed it was in development and has a lot of concept art created for it before they cancelled it.

History
The birds' designs was created by the developers when they where bored and eventually made into a trailer on April 1st, 2015.

The game ended up inspiring the game Angry Birds Evolution with the concept of evolving and caricature of birds, preferring to create many new birds instead of only using the core flock. It also was an early parody of The Angry Birds Movie.

This cancelled game served as an inspiration for the episode Piggy Farm in Angry Birds Classic.

Gameplay
The joke trailer proposes that the game's main mechanic is farming with a visual novel style storyline, along with other mini-games.
 * As Red, the player would make him move through the farm and do tasks, such as getting eggs from chickens.
 * As Matilda, she will shot at moles popping from the cabbage field by aiming at them, just like Whack-a-Mole, while avoid shooting the Blues accidentally. The gun shown in the trailer has a half star rating under it, and has limited shotgun ammo.
 * The player can dress Sasha Lynx in all sorts of clothing. Though it is not sure how this affects the game.
 * A game mode similar to Five Nights at Freddy's can be seen, wandering inside a dark barn with a flashlight. The Blues will try to jumpscare the player if the flashlight's battery runs out.
 * A visual novel-style story can be seen briefly, and the player can make choices to affect the story. Stella, Gale and Mighty Bagel were the focus in the story as seen in the trailer.

Characters

 * Red: A grumpy dwarf bird that lives on his farm, who has some anger issues.
 * Chuck: An old and cheerful fisher bird that lives on the farm. He is good with emotional support.
 * Bomb: A fat bird that wants to get fit, but also eats ice cream since it's his favorite.
 * Matilda: A muscular farmer who protects her vegetable garden from moles by shooting with her shotgun.
 * Sasha Lynx: A female toucan that likes to dress up and cares about beauty.
 * Stella: A strong athlete with quite skinny legs.
 * The Blues: They are crazy birds that invade the farm and fool around. The other birds are fine with their presence. Only one of them has legs.
 * Mighty Bagel: A pun on Mighty Eagle, he is a villain instead and wants to take over the land of the birds' farm.
 * Gale: Mighty Bagel's daughter that wants her father to have success and end up with the birds' happy lives. She was a good friend of Stella.
 * The Pigs: They appeared for a while in the farm gameplay as actual pigs. However, some concept art shows that they might have been related with Mighty Bagel.

Trivia

 * The game UI and sound effects are reused from Angry Birds Stella.
 * The concept art depicts Sasha Lynx wearing a loose top and hot pants. This might be because of her design in the trailer being too suggestive.
 * This game, Bad Piggies and Cryptobirdies are the only games in the Angry Birds series without the words Angry Birds in its title. However, Agri Birds and the Cryptobirdies are both joke games.
 * The title is a mix of "Agriculture" and Angry Birds.
 * The ending part of the trailer uses the soundtrack where Chuck stops the light beam from a magnifying glass with a blanket in Fired Up.
