The Cadou Parasite is a grotesque, organic entity with a bulbous, asymmetrical body that appears both fleshy and slightly translucent, revealing shadowy internal structures. Its surface is covered in pulsating veins and irregular, wart-like protrusions, with a slimy, wet texture that reflects light unnaturally. The parasite features several tendril-like appendages that twitch sporadically, suggesting a sinister, autonomous life. Its coloration is a sickly mix of purples, reds, and blacks, with occasional bioluminescent spots that pulse faintly in darker environments.
