The Frigid Series (Frozen Series in the European Wii version) is the eleventh series of treasures in the Treasure Hoard found in the game Pikmin 2. It is a collection of seven Christmas-themed objects. It spans from items 80 to 86 on the US version, 79 to 85 on the European version, and 78 to 84 on the Japanese version. All of these treasures are found in Frontier Cavern, probably to fit the winter theme of the cave.
