An alien parasite rubber duck, solid 3D model. Classic duck body as the base, but with a monstrous alien bursting out of its chest. Tentacles emerging in chunky, coiled shapes wrapped partly around the duck. One tentacle gripping the beak as if controlling it. Eyes wide and exaggerated for a possessed look. All tentacles thick and durable, with engraved ridges for detail. Overall creepy but cartoonish, watertight geometry, and no fragile thin part
