Mario, Tyra and Liza: Tyra Builds Sandcastles at the Beach

In this programme we drop in on three children who are all having a very busy day.

In Italy, Mario, who is seven, spends Saturday cleaning prawns ready for customers at his dad's fish shop.

On a hot day in Ghana, five-year-old Tyra cools off at the beach and builds a massive sandcastle.

And in Russia, seven-year-old Liza and her twin brother Styopa build a giant plastic tower, only to see it knocked down by their little sister Yulia.

We see that, although children live in different countries, may look different and speak different languages, the joys and challenges of childhood are universal.
