Create a cover for a children's eBook titled "The Urban Escapades of Trevor the Toad" with the subtitle "The Adventures of Old Mr. Toad: Modern Adaptation." The cover should feature a toad prominently engaging with urban elements like skyscrapers in a typical American city. The color scheme should be primarily white. The mood should be whimsical and adventurous with a playful, illustrated style. Use a fun, playful font for the title and subtitle, ensuring the text is well integrated with the imagery.
