"Over or Under? Help the caterpillar crawl under and the butterfly fly over objects by tracing the lines."

The task in the image involves helping a caterpillar crawl under certain objects and a butterfly fly over other objects by tracing the appropriate lines. Let's break it down step by step:

---

Part 1: Help the caterpillar crawl under each of these objects

- The goal is to trace the line under the objects shown.
- Objects to consider:
1. A yellow leaf
2. A red bench

#### Solution:
