Context
Popobawa is a shetani, a spirit. Its name joins popo, bat, and bawa, wing. It describes the dark shadow the spirit casts when it attacks at night, not its form. It is a shapeshifter, taking human and animal forms. Pemba had known it before, in 1965, shortly after that island's political revolution. One 1960s episode is said to have ended when President Sheikh Abeid A. Karume publicly challenged it.
