The Water Stone is an item in Paper Mario.


This jewel allows water to flow out of it when it Mario places the stone in the hole of Lily's empty pond. The Water Stone can be found by going though the grass maze where Rosie is seen holding it. However, she is quite found by the appearance of the Water Stone and doesn't want to give it up unless Mario brings her something that is more pretty than the Water Stone. Mario manages to bring her a Crystal Berry and Rosie is excited to have it and gladly gives up the Water Stone.
