Robson travels to Brasil where he attempts to catch deadly black piranhas in the Amazon river. He then makes his way to Rio Negro where he encounters pink river dolphins, and goes to the remote fishing community of Jaraua. The Amazon is the biggest forest in the world, covering more than half of Brazil. From the 3 meter long Brazilian Catfish to the 3ft long Peacock Bass, if Robson goes hungry in the Amazon, he'll only have himself to blame.
