Correct sentence: An echidna uses its super nose to feel a bug wiggle and then grabs it.
Why this is better:
- We start with the animal: 'An echidna'.
- 'Uses its super nose' shows how the echidna finds the bug.
- 'To feel a bug wiggle' is simple — 'wiggle' means 'move'.
- 'And then grabs it' tells what happens next.
Short and simple for a child: 'An echidna uses its super nose to feel a bug wiggle, then it grabs the bug.'
