He is a fanatic of the show "Spooky-Poo!", the show's parody of Scooby-Doo!. He is good-natured and friendly, but rather stern when it comes to rules and schoolwork. He enjoys desserts, and anything that Dave Read cooks. His character is based on one of Marc Brown's elementary school teachers.
• Rodentia Ratburn: Mr. Ratburn's sister, who once filled in for Mr. Ratburn for a day when he was sick. Her teaching methods are notably similar to those of Miss Sweetwater and Mrs. Fink.

Francine later explained that the reason Mrs. Pariso was mean was because she was lonely. She kind of ignored Francine and Prunella when they disturbed her. When Buster called her a witch, she didn't seem to mind it (unlike Francine) and told a story about how she had met a warlock once.

She loses hair from chemotherapy, which grows back by "Prunella and the Haunted Locker".
