Hearing the dragon still chasing behind her, Mocha kept running as fast as she could, not even caring where she was going as long as she could get away. Turning corners and eventually coming across another flight of stairs, she found herself very grateful for the natural speed most rabbits had on foot. Any slower and she was certain that she wouldn't have a prayer of survival. 

Dashing up the stairs, she looked around for an unlocked room and slammed the door behind her, relieved to find a lock that could be used. It probably wouldn't do too much good if the dragon burned the door, but at least she had a little time to figure something out.
