Sweet Cap'n cakes

Sweet Cap'n Cakes is a group of music-themed Darkners from the Cyber World. Although they initially oppose the party and fight them as a miniboss in Cyber Field, afterwards they become allies in the fight against Queen.

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 to the point that they rebel against the Queen for banning most music, as well as dancing to it. The band's rebellion is 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

K_K is, as he mentions, a CD player. He appears to be made up of two, stacked on top of each other, his head is green, with gold eyes and a purple handle. He has black, green striped arms and "spine" extending from the white boombox that is his body. He wears green pants with a belt looped through it and black boots, with gold laces and green soles. His hands are green, with gold bracelets on both of his wrists.

Cap'n's head is a cassette player. He wears yellow headphones with music notes (eighth notes) on each earphone. He has a purple cap which he wears backward, sunglasses, and a blue short sleeved hoodie with a purple bandana. He, like Sweet, has solid black arms and yellow gloves. He wears black pants with a purple belt, and purple shoes with white laces and soles. Unlike the other two, who have four fingers on each hand, Cap'n has five.

Sweet is made up of two mono speakers. The head speaker has a speaker cap that functions as an eye, with one gold iris and pupil. Solid black arms with yellow gloves extend from the body speaker. Clothes consist of a black hat which faces forward, a pair of dark gray headphones with gold accents, black pants with two gold buttons, or possibly volume dials, black shoes with gold laces and blue soles, and white socks with gold trim.
