Create a design with the following features: 1. **Theme**: Instead of a "404" error message, use "Oops!" in large, playful text. 2. **Characters**: Illustrate three diverse characters - one with short brown hair, one with curly black hair, and one with light brown hair wearing glasses. Ensure they are looking at a screen with a friendly expression. 3. **Background**: Change the background color to a soft beige for a warm feel. 4. **Screen Content**: Replace the content on the screen with a fun graphic, like a confused cat or a colorful chart, instead of a website error. 5. **Plants**: Use different types of plants—like a cactus and a sunflower—placed around the characters for added cheerfulness. 6. **Color Palette**: Use pastel colors for the clothing, like light blue, pink, and green, to give it a lighter, more inviting look. This alteration keeps the theme of confusion but transforms the mood into a lighthearted and friendly atmosphere.
