Since making his debut in 1999, he quickly became a favourite character both on and off the pitch in the town and further afield.
Off the turf, H’Angus has also supported scores of community and charity events bringing a smile wherever he goes.
With his big anniversary coming up, and football on hold for the moment, we have looked in our archives to bring you 21 pictures of him monkeying around.
