Treasures are the main collectibles in Pikmin 2, where they must be retrieved in order to repay Hocotate Freight's debt, and in Hey! Pikmin, where they help refuel the S.S. Dolphin II's Sparklium supply. These objects are usually day-to-day accessories used by real world humans. The concept of a treasure also exists in Pikmin 3, but only in Mission Mode, where fruits and other valuable collectibles are all referred to as "treasure".
All that is known about this creature stems from a few sightings deep underground. All reported sightings feature the same core set of details: a giant, viscous form with a clear, hazy sheen not unlike hard candy. One theory holds that it may be the ectoplasmic incarnation of a kind of psychic phenomenon, but as is usually the case with such theories, it is very difficult to prove. All witnesses report being suddenly overcome with fear upon sighting the creature, approaching a state of panic and near insanity. In fact, every report contains an inordinate amount of extremely vague details, which has led to suspicions that exhaustion and fear have caused some simple natural phenomenon to be viewed as a living creature.
