Jimmy has spotted something

In the midst of his morning chase the ball game Jimmy suddenly spotted/or heard something across the field; he had a personal choice - run off to investigate or continue playing. The game won out.

The extra is a view of the fenced field which he loves to play on, it used to be the local school's playing fields but they don't use it anymore and so dog walkers are allowed back on which they weren't when it was in use.
