That's a fun question! There's no planet with "wrinkles" in the way we think of them, like on human skin.

However, some planets have surface features that could be described as "wrinkled" in a way:

* Venus: This planet's surface is covered in vast, shield-like volcanoes and rolling plains. These features, especially the volcanoes, give Venus a somewhat wrinkled appearance.

* Mars: The surface of Mars shows evidence of ancient tectonic activity, creating features like canyons and ridges that resemble wrinkles.

Ultimately, "wrinkles" are a human concept based on our own bodies. It's fascinating to think about how other planets might have features that seem "wrinkled" to us, even if they don't have the same biological meaning.
