Art style: Pixar-like 3D.
Full-length view, the entire figure visible from head to the tips of all tentacles, standing upright and centered — Bubble, a tiny purple octopus with a round bulbous head slightly bigger than his body. He has smooth, soft lavender-purple skin with a slightly deeper violet gradient across the top of his head, and a paler pinkish-purple underside. Eight short, plump, curling tentacles fan out beneath him, the two front ones raised in an expressive dramatic gesture, tips resting lightly on the sandy seabed as his base. Huge round glossy eyes with big dark pupils and tiny highlights, expressive raised brow ridges, and a small open oval mouth mid-gasp giving a funny theatrical look. Cute rounded proportions, chubby and squishy. Bright sunlit underwater reef setting with soft coral, gentle bubbles rising, and rippling light filtering through blue water around him.
