The video shows a small, gray mouse moving around inside a clear plastic bag. The mouse is seen walking on the bag's surface, occasionally stopping to sniff around. The bag appears to be filled with some kind of brown substance, possibly food, which the mouse seems to be exploring. The mouse's fur is a mix of gray and white, and it has a long tail. The plastic bag is transparent, allowing for a clear view of the mouse and its surroundings. The video is shot in a close-up angle, focusing on the mouse's movements and actions.
