Once all the Mission Clues have been collected, the user will still need to collect 1000 Invention Points in order to enter the Time Machine Mission Control. The player must travel between three different floors in the mansion to find the clues.Д«otley, using his powerful sensory device, then determines which activities need to be played in order to retrieve the needed Mission Clues. Polly then appears on a monitor to state which robot she has sent back in time for the question and to list the four Mission Clues that need to be found for the mission. Winkle asks a historical question and Polly gives a surrealistic and humorous answer, such as saying that the first chewing gum was made from super glue. The user can also enter the Time Machine Mission Control and view the ' robot roost' without acquiring the Invention Points that would otherwise be required, but the Wheel of Invention cannot be played nor can the Time Machine be entered.Д®ach of the game's twenty-five missions (one for each robot that must be rescued) begins with the player selecting one of Polly's quiz questions from the TransQuizzer. The storyline ends at this point, but the user can continue playing the Mountain's activities for study purposes or for fun. Winkle decides to give her a quiz on Latin, which doesn't please Polly, as she's no good at Latin. Winkle states that she can't give Polly a test with the same questions twice. Winkle, via a video monitor, agree to let Polly take the quiz again, though Ms. At that moment, Professor Sparks arrivesВ home from the Inventors' Convention. For the extra credit question, Polly said that the universe began with Botley and she therefore wants to send him all the way back in time to the Big Bang, which would cause him to be destroyed. Once all the robots are rescued, Polly reveals her ultimate plan to use Botley for the extra credit question, which more than makes up for the entire quiz. After the player successfully unlocks the door and enters Mystery Mansion, Botley gives the player a utility belt for accessing various functions during the game.

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.
