Anime Octopus in a Mountain Cave

An adorable large-eyed octopus with expressive anime features sits on a slick rock inside a misty mountain cave. Bioluminescent blue-green fungi and glowing crystals line the damp walls, their reflections dancing on a clear cave pool. Stalactites hang from the ceiling while soft sunlight filters through a distant cave entrance, painting warm gold highlights and cool blue shadows. The octopus playfully extends a tentacle toward a ripple on the water, moss clinging to rocks for texture. Rendered in high-detail anime cel shading with crisp linework and cinematic lighting, inspired by Studio Ghibli and Makoto Shinkai.
