In the video, we see a small mouse running up a flight of stairs. The mouse is carrying a slice of pizza in its mouth. The stairs are made of concrete and there is a metal railing on one side. The mouse appears to be struggling to carry the pizza up the stairs, but it keeps trying. The pizza slice is a large piece with a golden-brown crust. The mouse is brown and appears to be alone. The video is shot during the daytime and the lighting is natural.
