Ol' Grandsappy

Ol' Grandsappy is an old tree in Paper Mario: The Origami King. Mario and Olivia encounter him in Whispering Woods when they sit on a tree trunk, which is actually Ol' Grandsappy. The Whispering Trees tell Mario that he is very sick because some Toads chopped him down. Mario then has to find a Soul Seed to help revive him. After Mario obtains the Soul Seed, he finds that Ol' Grandsappy has been ambushed and eaten up by some Paper Macho Goombas. Mario uses confetti on him to bring him back to life and gives him the Soul Seed, which makes him sing a song and grow into Sweet Sap Loggins, a large tree and a younger version of himself.

Happy & Sappy
When the Soul Seed takes effect, Ol' Grandsappy sings a song called "Happy & Sappy", with the Whispering Trees as the backup singers (indicated in brackets), while Mario and Olivia dance.

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 temple.
