Did it rain in Oz? It must have. They had agriculture (thus, a need for scarecrows) and even though some of the flora talked it nonetheless needed the same things plants do here – sunlight, oxygen and water. Okay, so if it rains in Oz then the Wicked Witch of the West can’t go outside when it rains. Basic premise, given, and that’s probably why she has all those trained flying monkeys. “Fly, my monkeys, and go down to the corner shop and pick up some malt liquor, a Soap Opera Digest and a lotto scratch off!” So, buying into the fact that it rains, she can’t go out, she sends the monkeys, I’m just going out on a limb here when I say that castle must have really reeked during the rainy season what with the musty smell of wet monkey permeating the upholstery.
Here’s hoping the Wizard had the Febreeze market cornered.
