Deep blue sweets

Deep blue sweets first appeared during the 2005 Halloween event and were not tradeable. During the event, players trick-or-treated children around Lumbridge. They could either trick them with their Zombie head to get some sweets, or treat to give them back. When eaten, steam came from the players' ears. They melted into chocolate dust after the update, and are now considered a nonexistent item. However if a player died before the update and then got back to their bones (this happened pre-Gravestones) and items after the update it was possible to keep them.
