The Warden is shown to have been digging holes growing up and does nothing else trying to finish the work of looking for the treasure of Kissin' Kate Barlow.
She inherited the land of Camp Green Lake and thought that the treasure would be found there. She went looking and would give anyone the day off if they came close. Whenever one of boys finds something interesting, he gets the whole day off just like X-Ray (Rex Washburn) did when Stanley Yelnats IV (Caveman) gave him the lipstick tube. When Stanley says that he stole Mr. Sir's sunflower seeds from his truck, she tells Stanley that she uses rattlesnake venom as nail polish. When she asks Mr. Sir (Marion Sevillo) if he thinks that Stanley stole the seeds, he says no and believes that Stanley is covering for someone. Then, she scratches him on the face with her rattlesnake venomed nails. Later, the Warden learns that Stanley and Zigzag (Ricky) got into a fight and Zero (Hector Zeroni) almost killed Zigzag. She then learns that Zero has been digging part of Stanley's hole and he's teaching Zero how to read so she tells them to stop. Zero then runs off and she thinks that he's dead. After Stanley leaves to find Zero, Stanley's lawyer comes to pick him up after finding Stanley innocent. When Stanley and Zero find Kate Barlow's treasure, she spots them and tells them about her past keeping well away because of the yellow spotted lizards covering Zero and Stanley. When the lawyer returns, the Warden lies about Stanley but Zero saves the day by telling the truth and explaining that the chest has his name on it. The Warden, Mr. Sir and Mr. Pendanski are later arrested, letting Stanley and Zero go home with the chest.
After Camp Green Lake
The Warden was later arrested for charges while running Camp Green Lake along with Mr. Pendanski and Mr. Sir. Her camp was officialy shut down after she got arrested along with Mr. Pendanski and Mr. Sir. After the camp was closed, the Girl Scouts of the United States of America decided to reopen Camp Green Lake as a Girl Scout camp.
