The Periwinkle (Bill Wallis) and The Hermit Crab (Geoffrey Palmer) reveal the funny side of life between the tides.

For the joke-loving Periwinkle, life is all about entertaining his neighbours as he roves around the rocks annoying the residents. But it's not all laughs as the Periwinkle reveals when he recalls his near-death encounter with a giant gull...

Meanwhile the Hermit Crab is stuck in its shell with a Ragworm who doesn't do the housework, a parasitic barnacle and an anemone on his roof, who spends all her time exercising so there's no peace 'down below' for the crab. And when it looks like life couldn't get any worse, a crowd of children arrive at the rock pool with their fishing nets.
