Dewey Dew-Night!: The Sidekick is a cartoon short written by Rachel Vine. It features Dewey and Louie Duck and Webby Vanderquack, and also mentions Gyro Gearloose, Donald Duck and Flintheart Glomgold.
Plot
Following her finding out about his pet project of a talk-show entitled Dewey Dew-Night, Dewey Duck has Webby be his next "broadcasts"’s first guest, planning to have her tell the viewers about an amusing incident that apparently happened in the Cursed Antiquities Room of McDuck Manor earlier that day. Things predictably go awry due to Webby's shaky understanding of how talk-shows work.
Flintheart Glomgold's appearance is bumped.
