Angry Birds (game)/Unused Content

Angry Birds Classic is the first Angry Birds game to be released and it got a lot of unused content as seen below.

Red's Mighty Feathers Part 3
In the files of the game, there are two unused sprite sheets for a third part of Red's Mighty Feathers as both of them are label as "SEING RED". The first sprite sheet includes sprites of pigs with scubas and deep-sea diving suits. One of them is with their original design, which is with the deep-sea diving suit and others with the Chrome design which are with scubas.

There are also air tanks, duck feet, a lily, a mushroom, cave helmets, (Which are unused designs of the ones found in Mine and Dine. There are also two more sprites from the same episode on the sheet) and grass forms.

The other sprite sheet includes sprites of Red using his ability and getting wet, as well as sprites of feathers and water effects. This strongly suggests that part 3 would introduce water in the game.

Leonard
There are some sprites of Leonard that were never used in-game, such as sleeping, sweating, crying, cheerful and other beta sprites. In fact, it's an edited sheet of King Pig.

Sauropods
In the Jurassic Pork background sprites, there are sprites for sauropods. However, they never appear in the levels' backgrounds, but appear in the cutscenes.

Cardboard Pigs
In the pigs' sprite sheet, there are sprites for cardboard version of the normal pigs. It was probably meant to appear in Mighty Hoax or the Tutorial, but the latter is more possible because of the design's nature.

They would probably act as normal pigs, just as the Scarecrow Pigs do. They doesn't have any injured sprite, meaning that they were only objects or would be instantly defeated.

Bad Piggies Objects
In the files, there are sprites for destroyed versions of the normal objects. In the game, the objects are only destroyed, they have only one state. There are also a pipe wrench and blue caps for the pigs that are never used in the episode.

Golden Trophies
In the files, there are sprites for golden versions of the trophy objects, possibly meant to be the 3 Star version of them or Golden Eggs.

Wooden Fuse
In the same sheet, there are two sprites for wooden fuses with red and golden tips. Possibly meant to be the reward for Short Fuse.

Puzzle Piece
Also in the same files, there is a sprite for a blue puzzle piece, possibly meant to be an icon, object or reward.

Year Of The Goat
In the files, there is a sprite for a button of the episode Year Of The Goat that is not used in the game and was probably meant to be released on the start of 2015, since this was the latest Year Of The Goat and it uses the Classic Designs. While not used in the game, a Chinese Version of Angry Birds Classic features this episode fully playable.

Moon Festival
In the files, there is a sprite for a button of the episode Moon Festival that is not used in the game and was probably meant to be released probably on the same year, since Moon Festival's button is in the same assets as the Year Of The Goat and it uses the Classic Designs or on 2016, 2017 or 2018, because it's also in the same assets as Bird Island and Tutorial. While not used in the game, a Chinese Version of Angry Birds Classic features this episode fully playable. It

Stella Level
There is an unused level in the game called StellaLevel (sic), which will refuse to load. The level would probably have featured Stella.

Bubbles
Bubbles's level, unlike Stella, is actually able to load properly. However, the level will always have a score of zero and the Slingshot is stuck under the ground. No Birds are included in the level either.

Design Update
There is an unused poster of a new update. It is a file with a poster that has a texture of buttons and a wood background.

There are 2 Chucks (Toons Design), 1 Bubbles, and 2 Minion Pigs (Toons Design). And it uses the background for the Red's Mighty Feathers levels. All of the characters use their Toons Designs. The sprites are very similar to Angry Birds Friends' new sprites and this could be a test for these sprites.

This poster was featured in the News tab (Paused Game Screen).

Poached Eggs
In the files, there's a tile set for a new design of Poached Eggs, that is more realistic, being oil painted. It would possibly be part of the update, however, it's not used anywhere. It also matches the new episodes' background scheme.

Tickets
Tickets could be used in the Mighty League in order to play the levels and could be found in the Bird Island levels (Which were replaced by Shockwaves). But in recent updates, they don't appear anymore in the game. They were deleted to make the game fairer.

Stickers
Some stickers were unused or retextured such as:
 * One featured a defeated Hal in a rectangular form as an icon. To obtain this sticker, the player had to use a lot of birds. This sticker was retextured to Red using the Slingshot as an icon. The form of the sticker is now a star.
 * One featured tickets in an oval form as an icon. To get this sticker, the player has to use a determined number of stickers. This was deleted because tickets are not used anymore.

Snow Cannon
In one of the Mighty League levels, there is a warning message saying that a sprite is missing. The name of the sprite is Snow_Cannon. It could be the Snow Cannon from the Angry Birds Friends Winter Tournaments. The message is the following;
