"This plate is needed for a music box to play."
The Music Box Plate (オルゴール盤 orugōru-ban ) was found in the Private Residence at Rockfort Island in Alexia's bedroom. Claire Redfield had to use the King Ant Object and Queen Ant Object to unlock Alfred's and Alexia's music boxes, take the Music Box Plate out of one, and put it in the other. Doing this revealed a secret passage to a hidden alcove room. Another one is found in the replica of the twins' private house in Antarctica. The same as the former applies similarly; however, gems are needed to complete the ants on top of their music boxes.
