With the magic net, Pilar, Breno, and Samba end up in the Amazon.
They meet Maiara there, who dreams of seeing the sea. Along the way, the friends help Breno not to succumb to Iara's charms, learn about the legend of the Amazon river dolphin, and face a forester who is destroying the forest. The forester faces the fury of Curupira and Cobra-Grande, while Samba is marveled by an ocelot. Flávia Lins e Silva's book, illustrated by Joana Penna, describes a beautiful adventure where the characters discover folklore, fauna, flora, and foods of the Amazon.
