Fun weapons are wieldable objects that have 0 or even negative combat bonuses. They are put in the game by Jagex for a bit of fun. There is a restriction in the Duel Arena that can be set so only fun weapons may be used in the fight. Fun weapons are generally released for holiday rewards, as the point of the holiday events are to have fun, without a reward that would give advantages to participants as opposed to non-participants. Some examples of fun weapons include:
