In the video, a small monkey is seen lying down while a person is holding a needle and threading it through the monkey's mouth. The monkey appears to be calm and relaxed as the person continues to thread the needle. The monkey's fur is a mix of brown and black, and it has a small face with big eyes. The person's hands are visible, but their face is not shown in the video. The background is blurred, but it appears to be an indoor setting.
