Gilda is the secondary antagonist of the Recess episode, "Prickly is Leaving". She serves as the assistant to Dr. Slicer, who is known to be the most evilest and meanest administrator in the school district. When Dr. Slicer is about to be assigned as the new principal of Third Street School as the current principal Peter Prickly is about to enter a job as a principal for the Spiro T. Agnew middle school, Gilda accompanies him as she writes down notes of his plans of turning the school into his very own authoritarian institution, such as tearing down the jungle gym and replacing it with a guard tower, creating a new school uniform and regulation haircut code, and applying cover paint to the main compound building to suit his purposes. Just like her boss, Gilda is shown to be outright evil in nature, even helping her boss creating a newspaper hat for one of the students, T.J., as a warning against him if he goes out of line. Dr. Slicer even leaves Gilda in charge of the playground, demoting the current groundskeeper Muriel Finster to being her assistant, much to Finster's dismay. Gilda sinks further when she announced to Finster that she will have to wear a grey dress while serving her and answer to her annoying whistle, much to Finster's anger. However, she and Dr. Slicer are defeated when Principal Prickly decides to stay being principal of Third Street Elementary, much to both Finster and the students' delight.
