If there’s a drop on your head and the rice is big, you know you’re in the interior. And by interior, I mean you’re actually inside someone. The rice is big because you’ve shrunk to a tiny size and are inside someone’s stomach. The drop on your head is actually digestive fluid.
While you’re in the interior of this guy, you hear him break out in song. He starts singing “Oklahoma” (おく) at the top of his lungs. The big pieces of rice slosh around as he sings and dances. “OOOOk-lahoma, where the wind comes sweepin' down the plain!”
