Here are three simple ways to say that sentence:
- The echidna sniffs out bugs as they move.
- When bugs move, the echidna uses its nose to smell and find them.
- The echidna finds moving bugs by using its nose to smell them.
How these changes were made, step by step:
- I picked shorter action words like "sniffs" and "finds" so the sentence is easier to picture.
- I tried different word orders (putting "when bugs move" at the start) to make the meaning very clear.
- I kept the main words simple: echidna, nose, bugs, move — good for a 7-year-old reader.
