Mrs Pinkerton is or was an anthropomorphic bird (possibly some sort of stork or goose).
Description[]
A teacher at Duckfoot Crossing in the 1850s, Mrs Pinkerton was a kindly old woman. She was once worried by what seemed to be some sort of mysterious green spot disease which had infected her students, and called Doc Swaller, who quickly realized that the illness was a fake and convinced the children to wash off the spots.
Behind the scenes[]
Mrs Pinkerton appeared in Doc Swaller and the Green-Spot Cure in 1984.
