Pikmin: Spark/Treasure Hoard

Refuse is the main collectible in Pikmin: Spark. They are similar to Fruit in that they are needed to be able to gain the ability to survive until the next day. But is also similar to Treasure as it contains a monetary amount of Sparklium tied to it. You need to be able to go to the next day so you need to collect these items to be able to continue. Refuse unlike the previously mentioned collectibles can infinitely respawn, although there is some Refuse found only in a few areas. Some Refuse can be dropped by certain enemies whiles others can only be dropped by a certain boss or miniboss, a few of which can only be battled a certain amount of times. This finite Refuse tends to be more valuable in Sparklium than others and tends to be story important. By collecting one of each type of Refuse you are able to fight the true final boss and gain the true ending of the game.
