She appeared in "Odd, Odd West" when Timmy traveled to the past to find what happened to the deed to Dimmsdale Flats. Because the town was so dirt poor, the people had to pay her for her babysitting services with the deed to the entire town. Eventually, a mysterious pink-cowboy-hatted boy called the "Masked Stranger" appeared in the town and challenged her for the deed. He defeated Vicky the Kid in a rock-paper-scissors duel.
Vicky the Kid still would not give up the deed, so Wanda dropped a wooden barrel over her and she lost the deed. The barrel was then kicked and she was sent rolling out of the town, yelling and vowing revenge against the Masked Stranger. Apparently she never found the deed, and may have left Dimmsdale Flats to raise a family assuming she is a direct ancestor of Vicky. She does not appear again in the series, however.
