When Zombies Attack

You refuse to open your mouth. This triggered a series of events which happened so fast that the event as a whole was hazy, but here is what happened in simple and easy to visualize phrases: The zombie gets angry. You get angry. The zombie tries to bite you. You try to bite the zombie. You and the zombie roll around furiously on the ground. You get shoved down a hole. After a while the excitement of the battle wears off and you find yourself in the sewers.
