Pikmin Evolution/Treasure Hoard

Refuse is the main collectible in Pikmin Evolution, as they act as the main source of Sparklium, which is essential to have. Refuse is comparable to treasures in that it is based on real-world objects, and fruits in that there are multiple instances of the same refuse. However, what truly separates refuse from both is that, after refuse is collected, another instance of it or an entirely different piece of refuse can appear in its previous place or close to it.

Certain refuse has a chance to be "pristine", noted for its brilliant shine. Pristine refuse yields fifty percent more Sparklium than its ordinary counterpart, making them even more crucial to collect.

Each piece of refuse is categorized under a different family, or collection, unified by a single common trait shared between each piece of refuse. Finding all refuse in a family increases the odds of finding pristine instances of refuse in that particular family.
