Mouk and Chavapa are in Argentina, where they meet Chaco. Chaco is a cowboy, or a "gaucho", as they're called in Argentina. His job is to gather up his herd and take his cows back to his ranch. Mouk and Chavapa offer him to give him a hand, but they will soon find out that herding cows isn’t as easy as they think.
Mouk and Chavapa are in Venezuela. In order to play in a surprise concert, they go in the forest with their friends Joropo and Raïna: they're looking for tarapas, fruits which are used to make maracas.
