Extra Track
After beating the story mode two times, you will unlock a nineteenth, extra track designed in the shape of a character. Note that this second completion of the mode must be done through a continuation of the game after having unlocked the extra character from the first playthrough.
Sixth Character
To unlock a sixth character to play as in the game, and make the character's associated tracks available for unlocking through the usual manner of playing through the story mode, you must first beat story mode once.
