Art style: Flat Design.
A tall, slender, teal-colored octopus with a large, bulbous nose and heavy-lidded eyes. He has four tentacles as legs and two as arms. He wears a simple, short-sleeved brown shirt. His expression is deadpan and unimpressed, with a slight frown. He is positioned in a whimsical underwater neighborhood with unique, stylized houses on a sandy floor. The lighting is soft and diffused, matching his mellow and cynical personality. The scene is filled with muted teal, brown, and sandy beige tones.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Flat Design" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Flat Design". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Flat Design" idiom, not in any other medium.
