Wheel of Invention

thumb|300px|right The Wheel of Invention is the activity at Time Machine Mission Control in JumpStart Adventures 3rd Grade: Mystery Mountain.

Once inside the Time Machine Mission Control, the user has to get past the Wheel of Invention in order to acquire a Time Key & enter the Time Machine itself, though Polly has apparently reprogrammed the Wheel so it's not just a quiz, but rather a quiz show called "Pollywood Squares". Here, Monty Monitor quizzes the user with questions that provide the point in time where Polly has sent the missing robot & which eventually reveal the correct answer to Polly's original test question.
