Time Traveller

You walk away from the machine, cerfully into the plains. You notice there is no grass, because it didn't exist at this time. You keep walking, sweating in the warmth, but there still seems to be no sign of a dinosaur. You turn to head back to the machine, but suddenly, there is a loud rumbling.

Disconcerted, you begin to run back towards the machine, and then you seea cloud of dust on the horizon. Suddenly, in terror, you realise what it is.

Stampede!

What are you going to do? You only have a few seconds to decide!
