1970s Retro Bubble Letter Design

Create a retro 1970s bubble-letter graphic design with text: "I SURVIVED" at the top, "67 DAYS" in bold colorful letters in the middle, and "OF SCHOOL" at the bottom. Include a pastel rainbow with clouds, smiling daisy flowers, and sparkles. Use thick outlines, flat colors, rounded shapes, and a cheerful vibe with a solid contrasting background.
