These beliefs are an amalgam of Catholic teachings, Tupi and other indigenous folktales and myths, and macumba—an African-Brazilian form of spiritism like voodoo. They believe in the curupira, a jungle elf (some say beautiful woman) who leads people into the center of the jungle because its feet point backward and the lost soul thinks it is leaving the jungle. They believe that the pink Amazonian river dolphin turns into a man at night and seduces young virgins.
