If you were thinking clearly you might have decided to just turn around and leave. Then again if you'd been thinking clearly you wouldn't have stepped into a closed exhibit in the first place. You are dumbfounded at the realism of the creature before you. You know it's just a machine, but the attention to detail is amazing. It twitches every so often and it's eyelids flutter occasionally. It even stirs briefly and scratches its great head with it's rear claw before resting again.
You see a few feet away from you a heavy door leading into the cavern. You can't imagine it will be unlocked, but are surprised to find that indeed it is. Figuring "In for a penny, in for a pound" you push the door open and walk in. You're nostrils are assaulted with a pungent and unpleasant smell. Dragon breath. These people are good. You step into the area and step closer to the thing. It stirs slightly but remains "sleeping".
"Amazing." you whisper to yourself. You gaze in wonder at the dragon for a few minutes. You take a step closer.
"Just amazing." you say again. You turn to leave when a giant tail lands in front of the metal door, blocking your exit.
"Thank you." a powerful voice echos behind you. You spin around to see that the giant head of the dragon staring straight at you. There is a decidedly feminine tone to the voice and, though you're not up on your dracoonic anatomy you get the distinct impression that the dragon is female. What's more you're suddenly fully aware that this is no animatronic creature. You back away from her in abject fear. You collide with the tail she had used to block the exit, the end of which curls around. Her body moves forward as well forming a loose circle around you.
"You had better explain yourself, little man." she says.
