Karloz and the Amazing Animals from the Amazon

Karloz loves animals and wanted to go to the zoo, but his parents were too busy to bring him there.

Since Karloz cannot go to the zoo alone, he thought that by having a pet to keep him company might make him happier and less lonely. He wrote his cousin, John, who lives in the Amazon Rainforest to send him an animal to be his pet.

What animals will John sent? Can the animals from the Amazon Rainforest thrive in a city?
