Ammonia Pine

Ammonia Pine is a minor villain in Darkwing Duck. She was voiced by Mitzi McCall.

Background
She is a former cleaning lady who worked at a research lab. One day she accidentally inhaled the fumes of an experimental bathroom disinfectant. The fumes had a strange effect on her and turned her into a cleaning-obsessed villain. She was later recruited by F.O.W.L. for their dastardly plans. She hates and is even afraid of dirt. She has a sister named Ample Grime, also a F.O.W.L. agent.

Ammonia Pine appears as the primary villain in only one episode, "Dirty Money" (the 3rd episode in production order). Her other two appearances - "Cleanliness is Next to Badliness" and "Dirtysomething" feature her paired with Steelbeak and Ample Grime respectively. She also makes cameo appearances in "Ghoul of my Dreams," "In Like Blunt," and "Time and Punishment".

Darkwing Duck comic
Ammonia also appears in the "Duck Tales/Darkwing Duck" Crossover story "Dangerous Currency" where she is a member of the "League of Eve-il" along with Magica De Spell, Cinnamon Teal, and Camille Chameleon. They are in an alliance with The Phantom Blot, "The Fearsome Four'", and The Beagle Boys. They are also later joined by Negaduck.
