Angry Birds (game)/Unused Content

Angry Birds Classic is the first Angry Birds game to be realesed and it got a lot of unused content as seen above;

Aquatic Episode
On the files of the game,there are unused sprites for an unused episode,there are sprites of pigs with scubas and deep sea diving suits,one of them are 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,an lily,an mushroom,cave helmets (Which are unused designs of the ones found on Mine and Dine ,there is also two ore sprites from the same episode on the sheet) and grass forms;which were probably meant to be used in the aquatic episode.

Stella Level
There is an unused level in the game called StellaLevel (sic). The level refuses to load. It is thought to be a level where you only use Stella, who was not included in the game back then.

Bubbles
Bubbles, unlike Stella, is actually able to load. However, the level is always messed up and will give you a score of zero. The Slingshot is stuck in the ground, so it is impossible to actually fling a bird. To add fuel to the fire, there are also no birds included in the level.

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 Chuck's  (new game design), 1 Bubbles, 2 Minion Pigs (new game design) and uses the background for Red's Mighty Feathers levels,all of the characters use their Toons Designs.The sprites are very similar to Angry Birds Friends's new Toons sprites.

Tickets
Tickets could be used in the Mighty League 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,mostly to make the game more fair.

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

On one of the Mighty Leagle levels,there is an warning message saying that an sprite is missing,the name of the sprite is Snow_Cannon,perhaps,the Snow Cannon from the Angry Birds Friends Winter Tournaments.
