A colorful, playful, gamified anatomy illustration of a cartoon character with muscles like biceps and pectorals labeled, featuring XP, a streak, and a description card.

Design a bright, playful, gamified Duolingo-style muscle selector with cute, friendly anatomy characters. The human body should appear as a simplified, rounded 3D figure with colorful, pill-shaped muscles that pop up when tapped. Each muscle highlights with cheerful animations, sparkles, and encouraging sound-effect icons. Use bold, fun colors—greens, oranges, blues, purples—with soft shading and big expressive labels. Add XP bars, progress streak flames, achievement badges, and a ‘Muscle Mastery’ level system. Muscles should bounce slightly when selected, showing a card with friendly descriptions, simple icons, and mini challenges (e.g., “Tap to learn 3 exercises!”). The overall vibe: joyful, cute, motivational, and highly accessible—like a friendly anatomy-learning game. See more
