Mystery Mountain is the setting of JumpStart Adventures 3rd Grade: Mystery Mountain. It is the "mountain mansion" home of Professor Sparks, his daughter Polly Sparks, and an abundance of sentient robots created by the Professor, including Botley, Mort, Mrs. Beasley, Bothoveen, Maestro Trombot, Egbert, Monty Monitor, and at least twenty-five other robots. It contains an abundance of extremely advanced technology, some of which is assumed to be standard for the universe in which the game takes place, many of which are the unique creations of the brilliant Professor. The Jumbo Electro Generator Room is responsible for supplying energy to the mountain. The stairs and the tram go to three different floors.
