This is like an animated Disney movie come to life. The main character is a retire postal worker. He has a workbench that he creates various projects on. Then, one morning, he notices that the clutter on the workbench from the previous evening has mysteriously been picked and placed in a box. It happens the next night and the next. Finally, this elderly gentleman, Rodney, puts an old black and white video camera in the shed, pointed at the work bench. He discovers that he has a little helper.
A little mouse was picking up little things that were scattered about and moving them all neatly into a box on the bench. Sometimes items that were twice the size of the mouse, like screwdrivers and clothes pegs.
Oddly enough, in 2019, Rodney had set up a camera in a friend’s workshop and discovered a mouse picking things up there as well.
