Intro. Lem was busy working at his desk, in his room, when he heard a "BOOM" outside his window that caused him to fall backwards from his seat. He looked out the window at his backyard to see something that had fallen from the sky, was it a living being or another rain rock? He quickly walked away from the window and ran down the stairs trying not to wake anyone, then quickly opened the back door and looked outside. Lem was a light green alien, who wore a red T-shirt and had antennae on his forehead.
