Mary Jane von Helfenpfelfer

Mary Jane von Helfenpfelfer was a resident of St. Olaf and a friend of Rose Nylund.

Helfenpfelfer took a vacation to Mexico and found a poor, scrawny, helpless little Chihuahua puppy on the street. She brought it home to St. Olaf with her, and she nursed it back to health. She took it to bed with her, and she taught it to fetch. However, when she took the puppy to get its shots, the vet told her that it was actually a rat.
