Create a playful illustration featuring four cartoon insect characters. Modify their designs as follows: 1. **Character 1**: A blue beetle with polka dots and shorter legs, giving it a stubby appearance. 2. **Character 2**: A tall, slender grasshopper with elongated antennae and a bright orange body with wavy patterns. 3. **Character 3**: A cheerful caterpillar with a green body that has vertical stripes and oversized round eyes. 4. **Character 4**: A shiny, winged ladybug with a purple body and starry designs on its wings. Incorporate whimsical elements in the background, like swirling plants and oversized flowers, without any brand references. Use a fun, coloring book style.
