The dentist.
He first looks at the T-Rex and then at you. As he sees you, you think
you see a sparkle in his eyes. Suddenly, he sprints to you and is
about to bite you!
But the T-Rex protects you. He roars loudly. You can't understand what
he's saying, but it seems that the Troodon fears him at least as much
as you do. Then he starts to examine the teeth of the T-Rex.
You enter the dentist's cave and see a Troodon standing there.
