Bongo Bongo is a mysterious Cyclopean shadow spirit with two large disembodied hands, and it serves as the boss of the Shadow Temple. Once sealed deep in the darkness at the bottom of Kakariko Well, the true origin of the beast is unknown. After Ganondorf came to power, the beast was able to escape its prison within the well and retreat to the Shadow Temple, where Impa went to try to seal it again.
