Panel 1: We find ourselves watching Lizzie and Christopher playing on the swing set. As they do so, our attention is drawn to the scraping noise made.
Panel 2: Having noticed that his swing is making a different noise, Lizzie calls Christopher's attention to that fact.
Panel 3: She does so by saying that their swings have different songs.
Summary: Aside from the improbability of a swing making a kaching noise, this is harmless enough.
