Sam's hat is an item that can be obtained by popping balloons that appear around Sam. It was originally obtainable during the celebration west of Varrock. Approximately every 45 minutes to one hour, balloons will spawn around the festival area in a similar fashion to the Falador Party Room. These balloons may be popped to potentially receive a Sam's hat, which will automatically be placed in the player's inventory.
If not already obtained in 2014, it could be obtained by balloon-popping when Sam appeared in the Lumbridge Crater on 3 July and 4 July2015 during the Summer Beach Party.
