Around the Wold in 80 Seconds

So, I was thinking: the planets in Super Mario Galaxy are tiny, right? Well, what if one planet like those, the size of two people's yards, was just like earth, only miniaturized and two people lived their lives on it? AND--better yet--they hated each other! A perfect setup! Only, plot might be limited, since there's nothing but two houses and a pond on the planet. Tell me what you think in a comment!
