Puree Puree no Mi (プレー プレー フルーイット) is a Paramecia-type Devil Fruit which allows the user to change the properties of an object by clapping their hands together in the form of praying.
This can also be called "Transmutation" (錬成 Rensei).
The user can transmute various substances (Water, Fire, Earth, and Air). However, if the user would try to transmute two elements/principles at the same time, he/she would experience stress and some may result in serious injury or death. Some transmutation will have time limits while some others will stay permanent.
