Thunder is Tricia's horse, whom she does love but is not ridden nearly as often as Nara's horse. She ensures that he is fed and watered by herself every day, and every couple of days she will brush him but other than that he is mostly in his stall of in the paddock. She always rides whenever Nara wants her too, and sometimes in the arena with their personal coach. She would like to event on him one day.

Thunder is 15hh, Bay, and 7 years old.
