From Pikipedia, the Pikmin wiki
The Worthless Statue (えらそうでえらくない石像?, lit.: "Authoritative-Looking But Actually Not Authoritative Stone Statue") is a treasure in Pikmin 2. It is actually a white king chess piece, and is located in the sixth sublevel of the Frontier Cavern. It may be found in the water or on the ledge near the hole to sublevel 7. Use Reds and Blues or the Bulbmin that are found in the sublevel. As the Pikmin are transporting the treasure, make sure to defeat the Cannon Beetles and Water Dumples in the level.
“At first, this object looked impressive, but closer inspection reveals it's just a cheap statue. In many ways, it reminds me of my father. Hmmm... I probably shouldn't tell him that.”
“Once, on an unknown planet, a megalithic civilization flourished, and this is proof of its existence! For hoarders of ancient artifacts, this is a must-have piece! Truly, collectors will crave it! (I do not know if that is true or not, but items in demand fetch higher prices.)”
