(This refers to the trio as a whole:) "The trio is portrayed as rebels that oppose the Queen's plans, but are often distracted by dancing and rambling each other with what they should do. The band loves music to the point that they rebel against the Queen for banning most music, as well as dancing to it. The band's rebellion is usually peculiar, as they would play loud music as a sign of rebellion, and some of the Darkners in Cyber Field often find their ways of rebellion interesting or weird. If someone else starts dancing, the band also dances with them as well." (Sweet Cap'n Cakes WIKI)

I don't have a preference for what they sound like...! Just be creative!

Good luck!
