Create a four-panel cartoon illustration in the classic 1969 Scooby-Doo, Where Are You! art style, featuring Bluey characters drawn true to their original designs but with Scooby-Doo visual elements: bold black outlines, muted vintage colors, expressive but simple faces, flat Hanna-Barbera-style backgrounds. Panel 1: Bluey confidently pulls the mask off a spooky villain to reveal Muffin underneath, who looks angry and is stomping or crossing her arms in frustration. Panel 2: The Heeler family (Bluey, Bingo, Bandit, Chilli) pose proudly beside their orange SUV, now repainted like the Mystery Machine (blue-green body, orange flowers, swirls), keeping the Heeler car shape. Bandit stands arms crossed, Chilli has a hand on her hip, Bluey and Bingo strike playful poses. Panel 3: Browny Bear (Bandit’s puppet) chases Bandit, Chilli, Bluey, and Bingo down a dungeon-like stone corridor with flickering torches, cobwebs, and damp stone walls. Everyone is in a classic Scooby-Doo exaggerated running pose, looking scared. Panel 4: The Heeler gang investigates a spooky haunted house or crypt; Bandit holds a lantern or flashlight, Chilli inspects clues, Bluey and Bingo huddle nervously. Use misty, dark backgrounds with spooky shadows and vintage textures.” See more
