Doc's hat is one of the most important objects relating to Doc because he regularly needs it to take on any task he has in mind. As to why his hat seemingly hold an endless array of gadgets, Doc even replied that it "comes with extra trunk space" (in the episode "Buckets"). He also has a mechanical version of his hat dubbed the Tells-Me-Who's-Knocking-at-the-Fedora that can tell who's at the front door in advance.


S1e24 sage doc hides a piece inside hat

Sage Doc places the indigo gem inside the hat.

It is revealed in "The Rock of Sages" that the hat was passed down to Doc from many generations as a heirloom. It originated from one of the Seven Sages that bore resemblance to Doc and was one of the locations that protected each part of the very powerful gem known as the Rock of Sages that led to the founding of Jollywood, and the hat is also known as the Conical Cap of Truth. However, in the Season 2 episode "Dr. Jingleheimer" Doc stated to the audience that his hat -- was stolen by the titular character to build a device to shrink the kingdom -- was his invention.
