One half is very positive and excitable, constantly smiling and the looking on the bright side of things. The other half is pessimistic and mopey, constantly looking sad and looks about ready to cry her eyes out. Both of them are known to constantly get any employee that enters their room to listen to them sing. Though, if anyone were to listen to their song, they will go mad. This allows them access to escape their containment and continue to sing to those who are near.
