Generate a vibrant and whimsical Halloween-themed image. The central focus should be a friendly, adorable monster, depicted as a small, fluffy creature with large, innocent eyes, a wide, gentle smile, and perhaps small, decorative bat wings or a cute horn. This charming monster is situated within a spooky but fun haunted house interior. The setting should include softly glowing jack-o'-lanterns, playful, transparent ghosts peeking from behind antique, cobweb-draped furniture, and colorful streamers or balloons in classic Halloween colors (orange, purple, black, green). The overall lighting should be dim but warm, creating a cozy and inviting, rather than terrifying, atmosphere, emphasizing a magical and playful Halloween spirit. Frame the scene using a medium shot to capture the friendly monster engaging with its enchanting surroundings.
