A berry tree from Generation II. MysteryBerries can grow on these trees.

MysteryBerries are a type of berry in Generation II. They restore 5 PP of a single Pokémon. MysteryBerry trees are found on Routes 35 and 45. Wild Cleffa, wild Clefairy, wild Clefable, and wild Mr. Mime may hold MysteryBerries. They can be obtained via Mystery Gift or by trading Pokémon from Generation I games. From Generation III onwards, Leppa Berries replace MysteryBerries, however they restore 10 PP instead of 5.
