At the front door, Polly contacts Botley and the player via a monitor, and says that she's recently changed the locks on the front door. After the player clicks on it, Botley crash-lands through the window, and tells the player about Polly's schemes.
The players signs in at the third grade school, and then appears inside a classroom. 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. 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. Set in a retro-futuristic universe, the game concerns Polly Spark, the bratty daughter of the world-famous inventor Professor Spark, and her attempt to alter history so that her inane answers to a history quiz she failed will be correct.
