2007[]
- the 2007 Christmas Event is released. Snow imps and various snowpiles flooded the world of RuneScape, and players could make snowballs (which could be thrown at other players, resulting in no damage) or make snowmen. Hats could be acquired from snow imps and placed on snowmen in order to animate them. This would reward the player with the Snowman Dance emote. Players could also be transported to the Land of Snow, and speak with the Queen of Snow to receive a snow globe.
