文字のない、かわいい3Dのハロウィン壁紙で、濃い紫の夜空を背景に笑顔のモンスターが3体います。薄紫のおばけ、緑の一つ目の生き物、角のあるオレンジのモンスターが、光るジャック・オ・ランタンの後ろに座り、キャンディコーンや包み紙のお菓子が並んでいます。キャラクターの上の紫の空きスペースに、あいさつ、名前、日付、パーティーの詳細を入れて、招待状やカードを作れます。

Create a finished landscape 16:9 Halloween wallpaper for a children’s tablet. No text, lettering, numbers, device frame, clock, icons, or app-screen elements. Use a festive, playful Halloween visual language: friendly rounded monsters and candy in bright pumpkin orange, slime green, and spooky purple, against a deep midnight-violet ground. Place one compact, clearly readable focal cluster in the lower center: three small, soft-edged monsters with distinct silhouettes—a smiling lavender ghost, a mint-green one-eyed creature, and a pumpkin-orange bat-eared creature—peeking among wrapped sweets, candy corn, and a few tiny pumpkins. Keep the monsters warm and welcoming, with simple eyes and smiles; no gore, fangs, weapons, or threatening expressions. Render the candy with glossy sugar-shell highlights, the pumpkins with subtly ridged rind and warm carved candle glow, and the monsters with smooth matte, softly shaded surfaces. Add only a few sparse star sparks and tiny bat silhouettes close to the focal cluster. Preserve generous low-detail negative space around all four edges for app icons, especially the left and right margins; keep the upper third calm and dark, with no bright hotspots or small details there. The focal cluster should occupy about the central lower 40% of the canvas and remain clear at tablet viewing distance. Crisp high-resolution illustration, clean silhouettes, gentle warm rim light, soft ambient shadows, bright color against dark ground.
