Yuna and Stitch discover that there's a treasure buried in the forest of Shadow Valley. Angel appears and decides to go with them. But when Gramma tells them the horrible legend of the yōkai Pilolo who lives in the forest, they decide not to go. But the treasure dwells on Angel's mind and she sets out to find it on her own. With the help of Kijimunaa, Yuna and Stitch set out to find her. They find her fallen into a deep coma, and they must now find out why.

Hämsterviel gets Jumba to absorb power from the Spiritual Stone so he can gain ultimate power, while Yuna plans to break a shrunken-down Stitch out of the American football-shaped container Hämsterviel put him in.
