"Create a playful and colorful 3D icon of a wallet in a cartoon style. The wallet should have a rounded, soft design with vibrant candy colors like pink, blue, and yellow. Incorporate shiny highlights and soft shadows to enhance the 3D effect, making it look inviting and fun. The overall appearance should be cheerful and friendly, with exaggerated proportions to emphasize the cartoonish feel. No additional elements or backgrounds, just the 3D wallet icon."
