The script
On a quiet stretch of beach, just after low tide, a hermit crab has a problem. It's grown. And its shell hasn't.
A crab without a good shell is a crab in danger. Gulls patrol overhead. Fish wait in the shallows. So when a larger shell washes up on the sand, word travels fast.
Within minutes, a line begins to form. Crabs of every size, arranged, remarkably, from biggest to smallest.
The largest crab moves in first. Its old shell goes to the next crab in line. That crab's old shell goes to the next. One by one, all the way down, every crab trades up.
(lighter)It's not a perfect system. There's shoving. There's a little cheating. But in the end, almost everyone walks away with a better home.
And the smallest crab of all, the one at the very back of the line, finally has a shell that fits. For now.

Coaching notes
- 'It's grown. And its shell hasn't.' sets up the whole story. Leave a small pause after 'grown' so the problem lands like a punchline.
- Darken your tone slightly for 'Gulls patrol overhead. Fish wait in the shallows.' and then lift on 'word travels fast' as hope arrives.
- Documentary narration leaves room for pictures. Let the pause before 'For now.' breathe, and say it with a hint of a smile, not as a warning.
Try it three more ways
- Read it as a children's science show host, bright and full of wonder.
- Read it as a sports commentator calling the shell swap like a photo finish.
- Read it as a hushed late-night nature special, close to a whisper, as if you might scare the crabs.
