Create an ancient chibi stone teddy bear statue with a weathered granite texture, moss patches, and fine cracks. The teddy holds a red heart, contrasting with the aged stone. Engraved runes on the base faintly glow, adding a mystical aura. Slightly worn facial features enhance its aged look. Ensure ultra-detailed stone surface precision, high texture fidelity, and clear polygonal definition. Designed as a low-poly game asset.
