Toaster
From Jenny Everywhere Wiki
Toasters are machines for making toast. Unsurprisingly they have come up in multiple Jenny Everywhere stories.
One Jenny Everywhere passed through New York and made her friend get a better toaster. (COMIC: When Casting Calls)
Another Jenny Everywhere had a robot toaster created by a local mad scientist. (PROSE: Paying it Forward, etc)
Jenny Over-There had her office toaster confiscated by Doctor Omega. (PROSE: The Tribulations of Jenny Over-There)
