The Oracle is a newspaper in Trolberg. It is first seen in "Chapter 11: The Jorts Incident", and is the second known newspaper in Trolberg (the first being the Trolberg Daily).
In "The Jorts Incident", Kaisa shows the newspaper to Hilda, David and Frida when they come to her in the Library in hopes of finding out where the Tide Mice summoned by Hilda in Season 1 ran off to. The front page article of the paper is about the snack company Jorts suddenly growing into a multinational corporation under the leadership of its new CEO Gil Jones. Hilda immediately recognizes Gil from when she met him that morning at the bus stop, and realizes the Tide Mice are with him.
Kaisa mentions that the Oracle will change its name to "The Jorts Gazette" next week, due to the Tide Mice increasing Jorts' popularity. It is unknown if this name change actually happened after Hilda and friends caught all the Tide Mice and broke their power over Jorts.
