Collection Obsession Series

The Collection Obsession Series is a series listed in the Treasure Catalog in. It consists of eight playing cards, six of which randomly change numbers in each playthrough due to being linked to the combinations needed to open certain safes, and a pile of gold nuggets (of which there are 470 nuggets). All the treasures in this series are worth, and an extra is given when the entire series has been collected.

Trivia

 * The objects in this series are all somewhat unique compared to other treasures in, as they all impact gameplay in some way.
 * Gold Nuggets behave identically to how they did in, with Pikmin needing to mine piles piece by piece to collect them. They can also be found, though rarely, inside of enemies or jars as separate, single nuggets.
 * The playing cards are used as codes for safes. The Courage, Power, and Wisdom Emblem provide the code for the safe in Hero's Hideaway, while the Love, Money, and Work Emblem provide the code for the safe in Dream Home. All six are randomized each game. The Deity's Portrait and Devil's Portrait don't impact gameplay directly, but are also found within the Dream Home and act as red herrings to the actual numbered cards.
 * This marks as the only time where the aesthetics of the treasure change between playthroughs and directly impact certain parts of the game.
