The floogy-wah is a part of the Gungan anatomy, usually kept concealed under Gungans' clothing due to its hideous appearance.
Not much was known about the floogy-wah, including its location on a Gungan body. It was, however, believed to be unique to Gungan physiology. Some historians attribute the existence of the floogy-wah to the desire of so many beings to commit genocide against the Gungans.
Xenoanthropologists across the galaxy wondered what the floogy-wah was for, but never spoke of their curiosity publicly, nor wrote about it in academic journals—for some secrets are best left uncovered.
