丸く親しみやすい3Dマスコット

Design an original friendly 3D mascot for {{service}}, based on {{motif}}. Give it one compact rounded body, a clear silhouette, simple expressive eyes and a small welcoming smile. Add one distinctive {{feature}}. Use {{palette}} colors, soft matte clay-like material, subtle surface variation and broad diffuse studio lighting. Show one full-body character in a relaxed welcoming pose, centered with generous padding on a plain {{background}} background. Make it recognizable at app-icon size. No resemblance to a named existing mascot, no text, logos, tiny decorations or watermark.
