Have you ever looked at a picture thinking you’d seen it all… only to discover a well-hidden detail? That little thrill of curiosity, that urge to scrutinize every corner, is exactly what an apparently tranquil mountain scene has in store. Three animals are cleverly concealed within it. Where are they hiding? Why don’t we see them right away? Just wait and see…
Visual challenge: why we love these hidden images

And when we know that three animals have slipped into the painting, one question haunts us: how do they remain unnoticed when they are right before our eyes?
First mystery: a well-hidden, loyal companion
Imagine a grassy area at the foot of a flowerbed. You might think you see just a few tufts of grass swaying in the wind. Yet, one detail catches the eye: a more rounded, almost soft shape that blends perfectly into the surroundings. Here, the artist uses natural colors and the lines of the landscape to conceal the silhouette of a dog.
To spot it, nothing is more effective than following the textures: the grass creates the illusion of fur, and suddenly, an ear appears. It’s often the first animal we identify… but only if we really look closely.
Second challenge: an animal with long ears
Some mountain features seem innocuous: a shadow, a rocky indentation, a darker area. Yet, this type of detail is ideal for a hare to slip by undetected.
In this illustration, the artist uses the natural contrasts of the terrain to create a slender silhouette, almost sculpted from the stone. To spot it, you have to squint slightly: you can then make out two small, erect ears, embedded in the rock face. This trick works because our brain first imagines a hare in a meadow… not clinging to the mountainside!
Third appearance: an unexpected goose
Who would think to scan the clouds for an animal? And yet, the latest surprise guest is hiding where no one would spontaneously look. In this scene, the shape of a goose blends with the white masses of the sky and the clear lines of a rock near the summit.
The artist uses a delicate technique: the silhouette is sketched with almost imperceptible contours. By slightly changing one’s angle of view—as if creating an optical illusion —a long, slender neck and a beak turned towards the valley appear. A discovery as subtle as it is unexpected!
