elderly man 3d model

Create a low poly 3D model of a funny elderly man (grandpa) in a cartoon style, similar to the art style of the Roblox game Dodge Granny. The model should have a simple, blocky low poly aesthetic with flat shading and minimal detail. He should look old but comical and slightly threatening. Appearance: short and slightly hunched posture, big round belly, wrinkled face with a grumpy or crazy expression, small beady eyes, large nose, no hair or very few white hair strands on the sides, bushy white eyebrows. He wears a classic old man outfit: a white sleeveless undershirt, brown suspender pants, and worn slippers. The model must be fully rigged and ready to animate with a standard humanoid skeleton (head, torso, two arms, two legs). Keep the polygon count low — this is meant for a Roblox-style game. No textures needed, just flat vertex colors in muted, warm tones (skin tone for the body, white for the shirt, brown for the pants).
