These evil Babysitters were hired by Mr. and Mrs. Turner when Vicky was too miserable to babysit Timmy. Unlike Vicky, these babysitters are far more evil as they actually wished to kill Timmy and eat his brains.
After Timmy and Wanda sabotaged Vicky's cheerleading try out and caused Winston Dunnsworth to reject her publically, she became too miserable to babysit. That night, Timmy's parents hired these babysitters. Timmy attempted to lock them outside the front door but their green clawed hands still punctured through the door and grabbed at Timmy. Timmy then realized that getting back at Vicky was not a good idea and tried to find a way to make Dunsworth fall in love with her and make her his babysitter again. Cosmo suggests looking into Dunsworth's diary and Timmy does so. He then finds out what color Dunsworth is afraid of and decides to enact his plan on getting Vicky to not be miserable anymore. They were not seen again afterward as Timmy was able to get Vicky to babysit him again.
