Terra Brasil - Trilhas

The tropical islands that lie between Asia and Australia are among the biologically richest on earth, and home to a vast number of plants and animals.

It all begins with Nauris’s painful disappointment – I am not in India, I am in Ukraine. But... That’s OK. He is ready for adventure and to ready battle Rihards. For the first time, the boys receive the show’s paraphernalia – the black box and the promising golden envelope. But there's not much in them – just a harmonica and 200 hryvnia or just about 7 Euro.

Nauris will manage to feed half of the district with Kiev cake, cross the Paton bridge, and step inside a soap bubble in a museum. Rihards will get to know the Klitschko brothers, run around a giant football stadium, and eat three Kiev hot dogs. But that is not all. They will be forced to make money on the street and to make the girls of Kiev laugh with their plasticine figurines.
