The marble statue is obtained by Yoshiki's party in front of the classroom 2-9 after they go back to the old schoolhouse. Shinozaki hands it to the group and they give it to Satoshi's group and they use it in the back room behind the music room to get access to the principals office. After you obtain the embryo statue, it is used to access a secret room in the music hall, by being placed on a man's statue, which contains a small gold key.
Kaori can find the marble statue in the Infirmary in the desk. It has to be collected along with the embryo statue in the ENDING RANK: A. playthrough, as well as collecting all Bad Ends in order to get access to the "THE FINAL NIGHTMARE".
This item is obtained during the events of the fifth chapter. The statue itself is not found but is rather given to Ayumi Shinozaki and Yoshiki Kishinuma by Yuki Kanno after her tongue has been given back to her, and the events surrounding her and the other children's death has been revealed.
It is also one of the two statues required for Satoshi's party to gain access to the infirmary.
- The marble statue is rod-shaped in the original CORPSE-PARTY and may have been intended to be a phallic symbol, considering the gender/reproductive symbolism of the puzzle overall. This was changed into a white marbled statue in CORPSE-PARTY ZERO. Finally, in Corpse Party, it is shaped into the form of Baphomet, the symbol of the satanic goat.
- In CORPSE-PARTY, the player must put the marble statue and baby statue between the arms of two statues representing a man and a woman. Should the player put the marble statue in the female statue, Satoshi will experience a sharp pain in his arm; dropping his HP down to 3 (but his HP will drop no further past that).
- However, in Corpse Party, the marble statue must be placed on the right pedestal in the fifth chapter and there is no penalty for choosing otherwise.
