The unicorns ran beside the trolls in the heavy rain because the unicorns and trolls loved to play in the rain together. The unicorns would slide in the water on their hooves and the trolls would leap long distances and fall into big puddles. Water would splash everywhere and all of the surrounding animals became angry with the unicorns and trolls. But before the angry animals could yell at them, the unicorns would quickly run away from the animals to continue their fun. The nearby animal villages were always warned of the unicorns and trolls playing in the rain, but none of the animals could ever catch the unicorns and trolls to punish them.
