Teddy, having about average strength for a sixth grader, managed to throw it strong enough to hit the first zombie in the right leg... Snapping it in half. Dark red blood oozes from the wound, both from the half of the zombie's leg still on and the half of the zombie's leg that lays on the floor. The zombie hops forward for about two seconds, before falling over and crawling like the ones that were hit by the trash can.

As he ran out the door, he would find himself in the schoolyard between the cafeteria and the main building, there being about twenty feet from him to the door to the main building. There are no students, but he could hear a faint moaning from around the corner to his right...
