I can't help but see a bullfrog in 业. Maud Younger finds that the climate in the elevator's bathroom are perfect for her new business: growing bullfrogs.

界 = 介 + 田 : Joan of Arc wants to leave this world and sets up a rocket launch field in the elevator's bathroom. The field looks like a normal crop field, except that there's a rocket in the middle and that the Joan of Arc marked the boundary with white and red tape.
