Humanoid creature with dark skin, swollen potato-shaped head, duck bill, and medieval religimous costumery growing out their body. Mammy nuns are more or less undestructible.

The Mammy Nuns were created by feeding mashed potatoes contaminated with synthetic mutagens to San Quentin prison inmates.

Coined by Frank Zappa in the early eighties for his bizarre rock opera, "Thing-Fish".

Anatidaephobia is defined as a pervasive, irrational fear that one is being watched by a duck. The anatidaephobic individual fears that no matter where they are or what they are doing, a duck watches.

Anatidaephobia is derived from the Greek word "anatidae", meaning ducks, geese or swans and "phobos" meaning fear.
