Happy & Sappy

"Happy & Sappy" is the song Ol' Grandsappy sings in Paper Mario: The Origami King when the Soul Seed takes effect, with the Sap Sisters as backup singers.

Later, in the Scorching Sandpaper Desert, Olivia can sing a shorter version of this song at the ritual stand. However, it does not do anything, and a different song must be performed to reveal the Fire Vellumental Cave. The song cannot be sung again after the cave is revealed.

The full song may also play in Shy Guys Finish Last in the Sudden Death round, where one word from the song is replaced with a question mark and the player has to recall what the word is by selecting one of four answers. The omitted word is "burly" (answer B), while the other three choices are "churlish", "swirly", and "early" (answers A, C, and D respectively).

The song can be played in the Sound Gallery in the Musée Champignon, where it is listed as song number 8.
