Sprayduck is a Key Item in Pokémon Diamond, Pearl and Platinum shaped in the likeness of a Psyduck. Exclusive to the Sinnoh region games, the Sprayduck is used to water Berries planted in the ground in order to produce more berries. It is similar in proportion and function to the Wailmer Pail of the Hoenn region. The effect of the Sprayduck can be enhanced through the use of Loamy soil and Mulch purchased from the Pick a Peck of Colors Flower Shop.
