The 2014 Valentine's Day event was an event celebrating 2014 Valentine's Day, and started on the 13th of February.
After speaking with the Lumbridge cook about Valentine's Day, players can give the cook a Chocolate bar in exchange for a box of chocolate strawberries. Opening a box of chocolate strawberries gives three chocolate strawberries. However, players cannot open their own box of chocolate covered strawberries; instead, a player can only open a box given to them by another player. This encouraged players to find a valentine.
