Pulling it all together, the most accurate solution looks like this:
Pillow β on the bed, matching the striped example
Book β visible on the blanket, on the wall shelf, and as a small book on the windowsill
Cup β the red-brown mug on the wall shelf above the bed
Egg β represented by the oval shapes in both the lamp stand and the bedside cabinet ornament
This puzzle works precisely because its objects arenβt hidden the same way. Some are real items simply placed in a busy scene, while others exist only as shapes borrowed from furniture and decor. The next time a hidden-object challenge comes along, it helps to look past the obvious form of each item and search instead for its outline, silhouette, and possible disguises hiding in plain sight.
