JumpStart Adventures 3rd Grade: Mystery Mountain is a personal computer game in Knowledge Adventure's JumpStart series of educational software. As the title suggests, the game is intended to teach a third grade curriculum. This is the only version of this game created and, unusually for Knowledge Adventure, was still being sold over fifteen years after its initial release in 1996. In 2003, it was included as the "Fundamentals" disc of JumpStart Advanced 3rd Grade. Set in a retro-futuristic universe, the game concerns Polly Spark, the bratty daughter of an apparently very wealthy inventor, and her attempt to alter history so that her inane answers to a history quiz she failed will be correct. To do this, she sends twenty-five reprogrammed robots back in time and, with her father conveniently away on a business trip, she takes over Mystery Mountain, the literal "mountain mansion" where she and her father live. The goal of the game is to help Botley, the robot assigned to keep Polly under control, save the world by retrieving each of the twenty-five robots and bringing them back to the present.
