A chibi Halloween illustration with no headline text, showing a cute ghost and a smiling pumpkin character in a cartoon style. Both characters float in front of a purple night sky with a crescent moon, stars and small haunted houses, and the ghost carries a jack-o'-lantern candy pail. Viewers can remake it with their own text, swapping in a party name, date, address or a trick-or-treat greeting.

Create one finished 2:1 horizontal matching profile-picture artwork, designed as two equal 1:1 squares side by side, each intended to be cropped and used alone. Use the same uninterrupted purple night sky across both halves, with no dividing line. Left square: one cute little chibi ghost, centered in its own half and safely inside a circular avatar crop; big rounded head, tiny floating body, shiny eyes with two white highlights each, rosy blush and a small playful smile. Right square: one cute chibi jack-o'-lantern, centered in its own half and safely inside a circular avatar crop; round orange pumpkin body, short curved stem, carved friendly spooky eyes and grin, tiny rounded arms. Each character is fully contained in its own square; do not let any face, head, or body cross the center cut. Pose them turned slightly inward toward each other, with matching scale and lively expressions, so the two avatars read as a pair side by side. Give the ghost a tiny candy bucket and the pumpkin a small curled vine, both simple and secondary. Render in recognizable chibi sticker art: super-deformed proportions, large heads, tiny hands and feet, thick even dark-brown outlines, flat pastel cel fills, one soft cel shadow under each head, gentle blush, glossy white eye and hair highlights. Use a shared soft violet-lavender night sky, with a few large, simple pale-lilac stars and tiny sparkles; uncluttered background with clear contrast around both characters. Soft even light, friendly spooky Halloween charm, bold readable silhouettes at small avatar size. Keep all key details within the inner 80% of each square for circle-crop safety. No words, letters, logos, borders, or extra characters.
