Bendy is a fan-made easteregg in Abandoned: Discovery Island, and other related FNaTI games.
Bendy the Dancing Demon, or more commonly known simply as Bendy, is from the horror game, "Bendy and the Ink Machine," and makes a cameo in A:DI.
Bendy has an appearance similar to the classic Mickey Mouse cartoons, his head makes a very slight "U" shape, as his horns on his head form them. However, his horns are crooked, and melted ink covers his eyes. He wears nothing, besides white gloves, bowtie, and black shoes. He often has a teethy grin.
Bendy will rarely appear in the Lounge, with no real trigger. He will just appear, and state "the creator LIED," and if the player happens to look in the Lounge at that time, the camera will be forced down, and Bendy will be in the Office. If this happens, the player's death by Bendy is inevitable, as if they try to open the Monitor, Hide, or even Shut Off the Power, a simple sound will play indicating they can't.
