There are six unused audio tracks in Super Paper Mario. The first one is named "Dummy_32k". Dummy plays the tune of World 1-1 from "Super Mario Bros 3." Another is named "b_happy_flower_44k_lp." It's name suggests it was going to be used for when Mario uses the Happy Flower item. The next audio track is called "evt_relax1_44k_lp." This track is a peaceful, relaxing tune. It might been planned for use near the end of the game. The 4th audio track is called "evt_stg3_open1_44k_lp." It was most likely going to be used for a opening of a level in World 3. The next is called "ff_corrrect2_e3_32k." This unused jingle's name suggests there was supposed to be more than one jingle. The final unused audio track is a jingle named "ff_fault1_32k." This was most likely going to be used when failing a Mini-game.
