Royal College of Oz
From Jenny Everywhere Wiki
In the 925th Universe, Professor Know-It-All was once a lecturer at the Royal College of Oz, later succeeded by Professor Wogglebug. (PROSE: Annals of the Jen: One Year of Jenny Over-There: Tetra-None Hepta-Oct and Doctor Know-It-All Talk it Out)
Behind the scenes
In the original Oz books, no “Royal College of Oz” is mentioned, and Professor Nowitall taught in a personal schoolhouse rather than a wider institution.
