The Mystery Orange Button is a button that, when clicked, leads to a random episode of The Annoying Orange. Ever since mid-Season 3, the Mystery Orange Button has appeared. At the credits, if a viewer clicks the Mystery Orange Button, it will take them to a random episode in the Annoying Orange series. There is also a Mystery Marshmallow Button, which was used only once in Ultimate Marshmallow Tease.
- On 煩人的橘子 (simplified as Fánrén de Júzi), the Chinese version of the Annoying Orange series, the Mystery Orange Button does not appear to work. This is because the uploader didn't tag the link that leads to a video from the button. The same goes for other foreign versions of the Annoying Orange series.
