The Grass Memory (Japanese: グラスメモリGrass Memory) is a type of held item introduced in Generation VII. It is one of the memories, which are associated with Silvally. It corresponds to the Grass type.
RKS System changes a Silvally holding this item to its Grass-type form. Item-manipulating effects (such as Trick and Fling) cannot give Silvally a memory or remove a memory from Silvally.
