"New sprite sheet specifications Grid: 4×4 (16 frames), arranged left-to-right, top-to-bottom. Tile size: 16×16 pixels each. Background: transparent. Facing: right for all frames. Palette: purple cap with cyan spots; amber body; bright green eyes; dark outline. Style: retro pixel art, no anti-aliasing, crisp single-pixel outlines. Animation timing: designed for a smooth loop at typical retro frame rates (e.g., 8–12 FPS). Exact 16-frame pose plan Idle start — both legs together, neutral body height, eyes forward. Push off — rear leg begins to extend; front leg slightly forward; tiny cap tilt forward. Step forward — front leg planted, rear leg lifting; body slightly lowered. Passing pose — legs close together mid-step; body at lowest point (bob). Front leg forward — previous rear leg now forward and planted; cap tilt reversed. Push off opposite — opposite rear leg extends; front leg begins to lift. Step forward opposite — opposite front leg planted; body lowered. Passing pose opposite — legs close together mid-step; body at lowest point. Return to neutral — legs together, body returns to neutral height; small eye blink or pupil shift. Repeat cycle with slight variation — same as frame 2 but with cap and body pixels shifted by 1 px to avoid exact repetition."
