4. You open the door and find yourself in a crowd at an amusement park. Many of the shadowy figures in the crowd seem to be wearing hats or headbands with mouse ears on them. As you explore, the crowds slowly become more aggressive toward you - rudely nudging you out of the way to begin with and increasing in aggression until they reach the point of attacking you on sight and trying to kill you. They will leave you be if you procure a set of ears and wear them yourself. Should you manage to get in line and ride one of the rides all the way through to the end, you will find yourself back out in the hallway. Most of the injuries you sustained in the park will have healed, but one of them will remain.
