Major celebrations surround the giving and receiving of these prized assets

And since the Toka only occurs once every three or four years

Everyone jumps at the chance to dress up

The dancing goes on for three days

Each village attempts to out-dance its neighbours in a display of friendly rivalry

You could say this is Strictly Come Dancing Vanuatu-style

In the past tribal rivalry was far more serious

On this island there were precious few wild animals to hunt

Pigs would have been essential protein

But if they died perhaps through disease

What else did the islanders have to eat

The great-grandparents of these dancers were cannibals

Life on an isolated Pacific island is eternally poised on a knife-edge

Nowhere is this more apparent than on the single most remote island in the Pacific

Easter Island

This tiny speck of land has an extraordinary story to tell

With new twists turning up still to this day
