Notes on time and place settings
- The research guide explains that they landed in the Amazon rain forest, near the Amazon river. This rain forest is primarily located in the nation of Brazil
- The only sign of human development is a single wooden canoe. This may suggest that they arrived in the Neolithic Era, a time very early in the growth of civilization. The Neolithic Era was the first time that humans migrated into the Americas.
- This is one of a few adventures in which Jack and Annie visit the Prehistory, the time before written languages.
- In terms of Internal Chronology, this takes place one day after their previous adventure, Night of the Ninjas.
