Bad Piggy Bank

Bad Piggy Bank was a payment system made in 2010 for the Android version of Angry Birds Classic. This was exclusive to the Elisa Mobile Carrier network in Finland. It allowed players to purchase the Mighty Eagle with the click of a button (or the tap of a finger) on Android. It also allowed players to remove ads on the Android version. In v2.2.0, it was removed due to the Google Play purchase system being added.

Trivia

 * A plush toy was made for the Bad Piggy Bank but it was never released.
 * Angry Birds plushies that were NFC compatible were also planned to be made. There would be NFC tags in the left eye of each plush, with the Mighty Eagle plush unlocking him in the game or other plushies adding money to the Bad Piggy Bank.
