"Have you been to Barrymore Boulevard in Los Angeles? Or Oberon’s Alley in Boston?" Clark asked. "I know that Potion Mistress Ivory Opal works out of her shop Tongues, Tails and Bubbling Brews in Oberon’s Alley. However, Barrymore Boulevard sees a lot of magicals aspiring to enter acting and I heard from a fellow masters student that magicals out there will often use polyjuice as a way to be transformed while on stage."
