Most descriptions agree the video is low-resolution, grainy, and heavily distorted. It allegedly features a young woman wearing a green shirt or a turtle costume (hence the name), performing repetitive, nonsensical actions in a dimly lit room.
End of report.
During the peak of sites like Rotten or early LiveLeak, miscellaneous files were often given innocuous names to bypass filters. It’s possible a disturbing video did exist under this name, but its actual content has been lost to time, replaced by exaggerated rumors. Greenturtlegirl-3.avi
