Create a vibrant comic book cover featuring a young boy in a yellow shirt, desperately reaching out as he tumbles through a colorful, abstract space filled with floating blocks. A small white dog accompanies him, adding a sense of urgency and companionship. The background should be a starry void, with dynamic lines suggesting speed and movement, capturing the thrill of an adventurous escape.
