Dug deep into the sand

The rescuers act quickly, trying to help, and we watch the effects of their efforts.

Hide-Away and Fingerbone pulled until their feet dug deep into the sand, and the muscles that stood out on their arms looked like the rope they were pulling.

Our victim isn’t out of danger yet. Almost there...

What you write at this point depends on your situation. How can your rescuers help?

If the solution is simple to describe (as in Storm Boy - just pull!) you can use the snippet to look at the details of the action (they pull - their feet dig deep - their muscles pop).
If it takes a little more to describe (as in Example 1 - notice me and go where I point!), you might want to use each part of the snippet to show a different stage of the action (She waves - he notices - he reacts)

Here are some examples.

Amelia waved frantically and pointed to a low lying window until he noticed her flailing on the street, giving her a panicked but confused look like someone who’d just heard bad news.

Xavier plunged an oar into the water and felt the whole kayak judder as it skidded across the seething tide like he was surfing across a ribbed sand dune.
