A celebratory yellow emoji face wearing a small cobalt party hat, blowing a curled paper horn while colorful confetti arcs around it. Use rounded 3D sticker modeling, saturated but harmonious cyan, magenta, and gold accents, and a soft peach background. Front-facing composition, bright diffused light, lively eyes, and a subtle floor shadow should create a joyful icon that reads instantly at small size. No text, no watermark.
