Doodles were removed in Build 28 following the change to the Journal system. The Code is still within the item system but there is no longer a recipe to make a doodle.
A quick drawing/message you made with a pencil and a piece of paper, it will take out a medium amount of boredom, stress, and unhappiness. It is crafted by putting a pencil and a sheet of paper in the crafting area. UPDATE: Following patch B27, Doodle can no longer be used to reduce boredom.
