Underwater Anime Treehouse in a Coral Reef

An anime-style illustration of a whimsical treehouse perched among a vivid coral reef underwater. The treehouse is built from driftwood and living coral, with coral-branch rails, a small balcony wrapped in swaying seaweed, a rope ladder, and warm lanterns glowing softly. Porthole windows reveal curious tropical fish; light filters through the turquoise water, creating shimmering rays and floating bubbles. Surrounding reef bursts with pink, purple, orange, and teal corals, sea anemones, clownfish, seahorses, and a friendly octopus weaving between coral tendrils. The scene uses soft cel-shading, clean lines, and bright, saturated colors to evoke a cozy, adventurous, magical mood.
