Easter eggs

 * On the calculator, if the summary's resulting digits are sequential by moving up or down in value by 1 (Example: 123456789 or 987654321), the classic "Flagpole" sound effect with the "End Level" music from Super Mario Bros. will play and a Toad will appear, accompanied with fireworks. Depending on how many digits the summary has, the number of fireworks will change. (Example: 9 digits equals 9 fireworks).
 * Also, if the summary equals the player's birthday (Example: August 4th (08-04) would be "804"), a text saying "Your Birthday" will be displayed and the "Flagpole" sound effect as well the "End Castle" music will play. Princess Toadstool will appear and three fireworks will explode.
