Dr. Marbles has discovered the blueprints of an unmade mechanism designed by his great-grandfather. It's purpose: to ensure Motherboard's full protection, and cure her of any ailment (such as Hacker's virus). Permanently.

To get the mechanism to work, however, they need five rare ingredients:
 * 1) A rare type of plant from Ecotopia.
 * 2) A rare type of music note from Melodia.
 * 3) A rare type of wheel from Radopolis.
 * 4) A rare type of diamond from Frogsnorts.
 * 5) A rare type of spark plug for the circuit board.

With obstacles ahead of them, and Hacker determined to keep his advantage over Motherboard from withering, things will not be easy for our heros.

Can they accomplish their mission of finally curing Motherboard of the virus with the power of math and friendship by their side? Or will Hacker be the one to take the crown?
