Nogginease is a substance that clears the mind and allows for more effective studying. It can be bought at Slurps and Burps. The elixir contains Limbium.
In Keeper of the Lost Cities, Dex made it to help him and Sophie study for their midterm exams and to stop Sophie from being too stressed about them.[1] Due to the Limbium, to which Sophie is deathly allergic, present in the elixir, Sophie has a near-fatal allergic reaction after ingesting it.
