 * Then, the app will close.
 * Reopen the app, and you've unlocked Smile!

Appearance
Smile resembles George, the early version of Red, but he's black and with a creppy face (that's not possibly stolen from SCP-087-B)

Smile's Involvement in Angry Birds
When you tap on the screen, he'll disappear, then after 5 seconds he'll jumpscare the camera (and the pigs) causing as many damage as the Mighty Eagle.

Trivia

 * There has been rumors that Smile also appears in other Angry Birds games (Seasons, Space, ect), However, any proof has to be shown.
 * This is based off an entry in the Angry Birds iceberg.
 * Smile isn't real. He can't hurt you.
