The episodes are heavily laden with comedy such as the impostor Doctor's name, Banto Zame, seeming to be an intentional rhyme with Panto Dame.
Banto Zame and Mel Bush arrive on Generios Eight to try to locate one of the treasures, The Shelves of Infinity (Unit ZX419).
The Assemblers are fooled long enough for the Doctor to arrive in the TARDIS, and Banto and Mel escape with the Shelves of Infinity.
Mentos appears in our universe as a small metal box that projects the holographic image of an old man which acts as its real world interface.
The box is actually a portal to a shadow universe which is populated by countless information collectors—research devices that travel through time and space, constantly seeking out the answer to any given question.
Eventually, the two factions which were vying for control of the Mentos device fought and wiped each other out, along with the codes that would shut down the Questioner and end the game.
Unable to disconnect the computer without ending the game, the Doctor tried to stump Mentos without success until he and Sally Anne Stubbins asked it what it did not know.
The first is a short scene in which The Doctor and Mel attempt to view the Queen's Speech on the Time and Space Visualiser.
