stylized axolotl 3d model

Create a stylized, articulated toy model of an axolotl, designed for 3D printing. The model must be a single, watertight mesh. Design it with clear, stylized segmentation into exactly 5 color zones for multi-color printing. Suggested zones: 1) Main body, 2) Head & face details, 3) Four legs, 4) External gills (rami), 5) Tail fin and dorsal fin. Ensure all parts have good connectivity and the design is structurally sound. The pose should be cute and static, but with joints (like between head and body, legs and body) visually suggested for potential future articulation.
