When spoken to, Father Christmas would give players a yo-yo, a toy that only players who attended the event can receive. If players lost their yo-yo, they could obtain another by speaking to him again. If the player already had a yo-yo, he would just wish them a merry Christmas.
Following the event, Father Christmas disappeared. If players needed a new yo-yo, they could obtain one from Diango in the Draynor Village market.
During the 2005 Christmas event, Father Christmas appeared at the gate east of Taverley, near Doric's house. When players were instructed to deliver a box of baubles to a person at the gate, they would find him there, although he was called "Hooded Stranger".
Santa Claus returned in the 2009 Christmas event. In this event, the Christmas-hating Ebenezer Scourge kidnaps him and steals the food prepared for the Christmas feast organised by the Queen of Snow. Scourge does this to seek revenge on the Queen of Snow.
Santa Claus is freed when players, wearing the Ghost costume, scare Ebenezer Scourge by pretending to be the Ghost of Christmas Yet to Come. If players wore the costume and talked to Santa Claus, he mistakes the player for a real ghost, but quickly realises that the ghost is the player.
For the 2010 Christmas event, Santa (badly) disguises himself as Fremennik called Thorvar Crittersmash and tries to bring Christmas to the Fremennik warriors fighting in Daemonheim. During the event, players had to collect items that Thorvar left in a dungeon when he was attacked by a "ferocious creature" (A heim crab named Salty Claws). According to Thorvar, he is a Fremennik, and Thok does not dispute this, claiming he is obviously a Fremennik as "he climbs through chimneys and into fireplaces, he is almost as strong as me". After completing the event, he teleported players to the Heimland Games and gave them a reward.
For the 2014 Christmas event, Santa needs the players help to construct and pull a giant Christmas cracker in the Lumbridge crater. This is achieved by travelling around the world and delivering presents for Santa every day and giving him the festive paper that he needs.
