Click and hold the mouse button to sing. Drag the cursor over a character to turn them nice again. Collect presents but watch out for jerktonium and coal. Don't sing to jerktonium, but sing to the coal to prevent it from hitting SpongeBob. At the end of a level a bonus chance may happen. There may be more presents falling for you to collect and give you more points. It may also be the ToyBob. Sing to him to defeat him. The game ends when you get hit by jerktonium or coal 3 times in a single round.
