Extra Lives
Before starting a new game, go to the fortune teller mode (in the toy box). Keep selecting cards until you get an "extremely lucky" card (it has Peach on it). This will give you 10 lives to start with instead of 5.

Fireworks
The way fireworks work is if the time that you beat the level ends with a 1, 3, or a 6, you get that many fireworks.
