The Monkey Propeller is a limited ultra-rare toy added to Adopt Me! as a part of the Monkey Fairground Event, which has ended. It is now only obtainable by trading and through opening Monkey Boxes. Like the other propellers, the Monkey Propeller propels the player upward. To stop the propeller, the player must jump.
The Monkey Propeller features a large banana tree that has a banana fruit in it and a monkey that was climbing and hugging the banana tree while holding a banana. The trunk of the tree is white and has 3 leaves on it.
