A super fresh minty clean announcement is an unlisted announcement video that was uploaded on August 26, 2011.
It is a short video that consists of the BFDI contestants saying that the Jacknjellify channel was hacked. However, it is later revealed that their channel wasn’t actually hacked, and the video was a prank. It only has two animated parts, one being when Leafy raises her hand, and the other being when the Announcer is talking. The rest of the video consists of still images of the speaking characters.
This video can be found in the "Announcement Videos" playlist from jacknjellify's channel.
