Pinhole and the expedition to the jungle

Pinhole and the Expedition to the Jungle is a story that has it all; plate tectonics, jungle survival and jokes. The so-small-as-to-be-almost- invisible Pinhole and four ill matched explorers take on the adventure of their lives in a tropical Indian forest. They find an outdoor tribe living in a freak geological fold formed million of years ago by continental drift, and they help the tribe make friends with an unusual visitor.
