- This article is about Pikmin 2 treasures. For the Pikmin franchise, see Pikmin series.
Series are the groupings of treasures. Each treasure is categorized into a group where the treasures there are related to one other in some way. For example: the Joy Receptacle, Danger Chime and Spouse Alert are all in the Frigid Series because they all are found in an icy cavern and sport a Christmas theme. There is a total of 26 series across the three versions of the game.
Once all the treasures in a series have been collected, the player can enter the Treasure Hoard, where the Hocotate ship will announce that that series has been completed – with a different announcement for each series – and will then create a sales pitch for each of the treasures in it. This can happen for more than one series at a time. Although, if the player enters the Treasure Hoard on a day after they have completed a series, and they have also collected any other treasure in the meantime, the Hocotate ship will not give the announcement the sales pitch. In the Treasure Hoard, each series has its treasures' icons with a blue or green background, with the colors alternating throughout the list.
