Sienna and the
Secret Treasure Cave

A seaside adventure awaits…

It started with something in the sand.

Three discoveries, one afternoon at the seaside — and a whole day that turns into a treasure hunt.

Sienna crouching on the sand, lifting an old green bottle crusted with barnacles, with a rolled paper inside it. Pippy and Tiggy lean in to sniff.

An old bottle.

Half buried in the wet sand, crusted with barnacles — and something rolled up inside it.

Sienna and her family kneeling on a striped picnic rug at sunset, unrolling a worn treasure map marked with a dotted path and a compass rose.

A mysterious map.

Unrolled on the picnic rug, soft with age, marked with a path nobody has walked in years.

Sienna walking a narrow clifftop path above breaking waves at sunset, with Pippy and Tiggy running ahead towards a dark cave entrance in the rocks.

A secret waiting to be found.

Along the clifftop, past the rocks, to a dark little doorway in the headland.

Meet Sienna, Pippy and Tiggy.

  • Sienna, a small girl with long fair hair, in striped blue dungarees and bare feet.

    Sienna

    Curious, brave and always ready for adventure.

  • Pippy, a small fluffy cream-coloured puppy with a blue collar.

    Pippy

    Small, fluffy and always ready to help.

  • Tiggy, a golden retriever puppy with a blue collar, mid-bound.

    Tiggy

    A little bundle of energy with a very waggy tail.

Follow the map.

Seven stops between the picnic rug and the treasure. Sienna walks every one of them.

Where will the map lead?

Past the rocks, through a gap too small for grown-ups, into the dark. Pippy goes first. Tiggy is not so sure.

And then, right at the back, where the light only just reaches — something glitters.

The inside of the cave, lit gold. Sienna and her dogs at the entrance, with coloured crystals and scattered gold coins glinting on the cave floor.An open treasure chest spilling gold coins and jewels, with Sienna and her family gathered around it in the glittering cave.
