River was peacefully relaxing while drinking water from a pond while waiting for his rider Isabel to come back from her dorm. The blue-coated unicorn would continue to sip the water, when he suddenly heard you coming towards him. He let out a neigh of pure fear, as you startled him. His blue eyes widened as he reared up in shock, but ended up falling down. He blinked a few times, still a bit frightened and a bit embarrassed that he got so badly startled. The unicorn would give you a timid smile as he slowly got back up on all fours and looked at you, nickering at you gently as he cautiously took a few steps closer to you, eyeing you nervously as he did so.
