Agnes Scullarzo is the crazy and obnoxious grandmother of school bully Boyd Scullarzo who often comes to school to embarrass him by publicly sharing humiliating stories about dolls he played with when he was a kid, bunny underwear he still wears, and stories about her having trouble getting a thermometer in him. She is unaware of how the stories embarrass him and just thinks she's getting a laugh. She also is a professional wrestler and is the rival of Pelswick's grandmother "The Masked Prune"
