In the video, there is a small brown mouse standing in front of a blue door. The door is set into a tree, and there is a stone step in front of it. The mouse is standing on the step, and it is looking up at the door. The mouse then starts to climb the door, using its tiny paws to grip the door's surface. The mouse climbs up to the top of the door and then climbs back down again. The video is a loop of the mouse climbing the door and then descending back down.
