Clay skulls are an item used to decorate the painted coffin in the Festival of the Dead event. Three are required per offering made in the event. A total of fifteen skulls are needed to do all of the tasks in the event.
Skulls are made by crafting soft clay in the inventory, using one piece of clay per skull. 10 Crafting experience is granted for each skull made. Unlike most clay items, the player does not make them on a potter's wheel but instead makes it simply by clicking it in inventory like clay rings. They also do not need to be fired at a pottery oven.
- The blue dyed skull looks exactly like a sugar skull, a discontinued item from the Squeal of Fortune.
