Hey Presto was a wizard who arrived in RuneScape after chasing the Party Demon down. He was located in three areas, one was north of the demon by the east entrance to the Barbarian village near Varrock, one was south of the demon by the entrance to the Varrock Sewers, and one was north of the demon in the Bandit Camp (Kharidian Desert). Talking to him gives you a Boogie bow. This could be used to kill the constantly spawning party demon, though it gave no ranged experience. Once a player had killed a party demon, they could talk to Hey Presto to obtain a pair of 200m glasses. He also mentioned funny things about partyhats and Party Pete.
