Did you get it right?
The clock-tower maintenance room hides a washer, matchbook, feather, and frog.

The Answer
The correct answer is: the washer, matchbook, feather, and frog-shaped oil stain on the floor.
Here is why
- The washer is partly covered by the large wrench on the workbench.
- The matchbook leans behind the clock-oil can near the window.
- The feather rests against the stair rail above the gears.
- The frog is formed by two gear-like eyes and the broken oil-stain outline on the lower-left floor.
Why people miss it
The engraved gears create many circles, while the frog is not a separate object. Its body is interrupted by floorboards and irregular oil marks.
