Despite being an avid wildlife photographer, retired postman Rodney Holbrook never expected to capture a Ratatouille-style scene unfolding in his own shed.
After regularly discovering that things from the night before had been mysteriously tidied, he set up a night vision camera on his workbench.
It captured a mouse picking up clothes pegs, corks, nuts and bolts.
He has since nicknamed the well-kept rodent Welsh Tidy Mouse.
