Sweet Cap n Cakes
The trio is portrayed as young rebels that oppose the Queen's plans, but are often distracted by dancing and rambling to each other with what they should do. The band loves music and rebels against the Queen for banning most music. If someone else starts dancing, the band also dances with them as well.
Sweet is the energetic one who looks up to K_K.
Cap'n is the smooth one who looks up to K_K.
K_K is the silly one who looks up to the other two. They all are rebelling against the Queen.
