In this issue, we travel to the tropical rainforests of South America, with their strange and magical sights and sounds. David journeys for three days, to get to a remote part of the forest deep in the Amazon. Learn how he investigates the health of leaves growing at the tops of trees that are 40 m tall. (That’s taller than a 10-storey building!) Then join Pizotito and Paquita as they discover the diversity of animal life in the Costa Rican rainforest.
