The forest floor is perhaps the worst and most inhospitable place of all - dark, damp and full of potentially dangerous wildlife, and nowhere is more forbidding than the original heart of darkness, the Congo. This is an undercover world of subterfuge, secrecy and camouflage. Nothing is what it appears - venomous snakes look like leaf litter and invisible flies carry fatal diseases. Through the chimps and gorillas that live here, Charlotte reveals the problems of surviving in this difficult place. They need nests to keep them off the forest floor at night, and they need to know what is edible and what will kill them.
