Soul Seed

The Soul Seed is an item in Paper Mario: The Origami King. The Soul Seed begins as the Shriveled Seed, and is located in Whispering Woods in a section of a tree that can be opened using the 1,000-Fold Arms. The Soul Seed can be revitalized by throwing it into a spring located in Whispering Woods. It can then be given to Ol' Grandsappy, which causes him to regain his energy and grow into a tall tree again.
