Kids Reward Sticker Design: Polite Panda with ‘Used Magic Words!’

Create a line-art style vector illustration of a cute panda encouraging politeness with a speech bubble saying ‘[placeholder]’. The design should have bold outlines, no shading or gradients, on a pure white background, suitable for die-cut stickers for children’s rewards. Focus on creating a friendly, approachable character in a high-contrast format that is simple to cut and reproduce.
