"Create a cartoon-style Halloween illustration featuring a blue and gray dog character wearing a ghost costume made of a white sheet with eye holes. The character is holding an orange pumpkin candy bucket with a jack-o'-lantern face, filled with candy. The character has wide, expressive eyes, and its hands are raised in excitement. Above the character, write the word 'BOOEY' in bold, wavy orange lettering, with a spider hanging from a web connecting to the text. In the background, add a large orange moon, with two black bats flying across it. The design should be vibrant, playful, and clear, suitable for a T-shirt clipart with a transparent background. No additional text should be included."
