Create a whimsical illustration featuring four cartoon insects. 

1. **Insect Design Alterations**:
   - Change the first insect to have shorter antennae and polka-dot patterns on its body.
   - For the second insect, make it a butterfly with bold stripes instead of spots and larger wings.
   - Transform the third insect into a ladybug with elongated legs and a smiley face.
   - Make the fourth insect a dragonfly with thin wings and unique swirl patterns on its abdomen.

2. **Background Elements**:
   - Introduce swirling lines and abstract shapes in the background, creating a playful garden scene without any recognizable brands.

3. **Expressions and Features**:
   - Ensure all insects have cheerful expressions with prominent, exaggerated eyes.
   - Incorporate bubbles or floating shapes around them to add a lively, dynamic feel to the scene.
