Jenny is Joe's girlfriend in Once Upon a Wintertime, the segment from Melody Time. She is a lovely and sweet young lady, but as she is not quite so skilled a skater as Joe, becomes swiftly annoyed at his playful pranks.
Jenny and Joe spend time with each other during winter time riding on a sleigh (along with animal couples following them). They later spend time ice-skating together ice skate but when a near-tragedy ensues on thin ice after Joe smirks at her falling as she separates from him, Joe was able to rescue her on thin ice. After rescuing, she and Joe reunite with each other riding on their sleigh again as the woodland animals bid a farewell to them.
