Agatha is the mean nanny who bullied Jessie and Zuri in the episode World Wide Web of Lies. She ran a blog called Toddler Tattler, where she posted out of context pictures that made Jessie and other nannies look like they were very bad at their jobs. However, Jessie and Christina Ross blackmailed her into taking it down. Agatha is similar looking to Nanny McPhee from the film franchise, Nanny McPhee, but their personalities are completely different. She is portrayed by Jennifer Veal.
