Eight children from the UK travel to Madagascar to learn how they can help the island's wildlife. The team kayaks down river to reach the island's most famous national park.

The team heads west to Ranomafana, Madagascar's most famous national park. To get there they have to kayak down river and work as a team for the first time. They then split into teams and 'bio blitz' two areas - one that has once been disturbed by people and the other entirely pristine - to see which area has the most wildlife. The results surprise them.
