"Santa is watching, so be good!" は、遊び心のある絵本風のタッチで描かれたクリスマスのキャラクターポスターです。赤と緑の丸い文字が2行に並び、その下で、ウインクするサンタがヒイラギとリボンの飾りが付いた木の窓から顔をのぞかせ、白紙の巻物を持っています。見出しを自分のメッセージに差し替え、巻物の文字や色を家庭や教室に合わせて変えられます。

Create a finished square Christmas quote image for a children’s playroom: bright, joyful, charming, and easy to read at phone-thumbnail size. The exact, only text in the artwork is: “Santa is watching,\nso be good!” Preserve the wording, capitalization, comma, and exclamation mark exactly; do not include quotation marks, a source, or any other letters or words. Make the quote the clear hero, centered in the upper half with generous safe margins. Use rounded, hand-drawn chunky lettering with broad strokes, soft corners, open counters, slightly bouncy baselines, and friendly, clear spacing. Set “Santa is watching,” above the larger, emphatic “so be good!” in vivid candy red and evergreen, with warm cream highlights and a subtle golden shadow for separation. Below the lettering, show a cheerful cartoon Santa peeking around the edge of a cozy, toy-like window, holding a long curled list with completely blank paper—no writing, marks, or symbols. Give Santa rosy cheeks, a warm smile, bright eyes, and a playful wink; make him inviting, not stern or spooky. Frame the window with a little festive garland and a few simple star and snowflake accents, leaving plenty of uncluttered pale mint and warm cream background around the text. Use clean, crisp outlines, flat playful color with gentle soft shading, and a polished illustrated storybook finish. Keep all lettering and the key illustration comfortably inside the square’s safe margins. No extra Christmas motifs, no busy background, no watermark, no additional text.
