I'm Sweet.
The ladies call me Cap'n!

Sweet Cap'n Cakes

Sweet Cap'n Cakes is a group of music-themed Darkners who first appear in Chapter 2. These "young men"[1] are initially antagonists and a miniboss in Cyber Field. After the encounter, the rebels are allies.

After their battle, the trio appears as shopkeepers in the Cyber Field. Their wares are:




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


Cap'n’s head is a cassette player. He wears yellow headphones with music notes (eight 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.

K_K (Cakes)[]

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.


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.

Main Story[]

Chapter 2[]

Sweet is often seen throughout the overworld in Cyber Field attacking Kris with piano tile-like attacks in certain areas, while Cap'n and K_K are seen selling CD Bagels and trying to confound the party on the teacup rides.

Near the end of Cyber Field, Sweet, Cap'n, and K_K reveal themselves as rebels against the Queen, challenging the party due to the trio thinking they had assisted Queen in capturing Noelle. The gang rambles about what they should do with the Lightners before starting to dance. The party begins to walk away, only to be caught by the rebels and begin an encounter.

Sweet, Cap'n, and K_K can be danced with during the fight. If the party uses Dance or DanceX after some time or Kris is knocked out during the fight, Susie starts wanting to dance herself. However, Ralsei says that only Kris could allow Susie to dance, as Kris's special ability is to ACT. Susie says that she isn't stupid enough to not know how to dance herself, and learns S-Action, allowing her to dance. Ralsei learns R-Action against his will, and is also able to dance.

When the party makes all the enemies dance, the group has a little dance party with them, with some fireworks spelling out Battle Won at the end, after which Sweet, Cap'n, and K_K keep dancing. Susie says that the fight is over and the gang is surprised thinking that they lost, but Cap'n said that their dance moves totally beat the party and that it was so good that they joined the good side, essentially gaining the trust of the rebels. The party and rebels become friends before the latter fly off on their rocket-powered DJ.

After the battle, Sweet, Cap'n, and K_K can sometimes be seen flying along with the heroes as they progress through Cyber Field.

In their shop in Cyber Field, Sweet, Cap'n, and K_K reveal that they rebelled because the Queen banned all music except for reverse diss tracks (songs that praised the Queen and said negative things about the singer) and noise music. They also reveal Queen used to be nice, or was mean but became crueler after another Dark Fountain formed and she became insane due to the Knight.

Normal Route[]

After Queen gets her giant robot, Sweet, Cap'n, and K_K and the rest of the recruited Darkners join the heroes to make a giant thrashing robot to fight against Queen's robot.

If enough enemies are recruited, Sweet Cap'n Cakes play music on request in Castle Town.

In Battle[]


Three attacks are used in battle. All of these come in sync with the background music.

  • Circle-shaped bullets that leave a trace behind them fall from the top, "spoken" from the drawings of the band members.
  • Musical note-shaped bullets fly from the speakers on both sides of the Bullet Board, moving slightly downwards.
  • Vertical wave-shaped bullets leaving a trail fly from the speakers on both sides of the Bullet Board.
  • Wave-shaped bullets fire in an explosion from the speakers on both sides of the Bullet Board.


When one band member's HP drops to 0, they spend a turn to fully heal up. To win the battle, one needs to make all band members dance.

At first, the battle appears unwinnable due to only Kris having access to the Dance(X) ACT, which only works on one enemy, and all the enemies snap out of dancing in no more than 2 turns. After a few failed attempts, both Susie and Ralsei are revived if they're down, and Susie questions why only Kris gets to ACT. After a dialogue Susie gains access to S-Action before forcing Ralsei to gain access to R-Action. If Kris is down at the time, special dialogue plays about Ralsei not needing to revive Kris to dance. It is then possible to make 3 party members dance with 3 different enemies in one turn and win the battle.

  • Their relation to each other is unknown/up to interpretation, as stated by Nelnal, the guest artist who designed them.[2]
  • Sweet Cap'n Cakes are designed by the guest artist Nelnal.[3]
  • In a tweet that has since been deleted, guest artist Nelnal referred to Sweet Cap'n Cakes as brothers. However, Nelnal later recanted this statement.[2]
  • The name of the trio and their related song When I Get Mad I Dance Like This is inspired by the Homestar Runner segment "Sweet Cuppin' Cakes."[4]
    • The song referenced in the Homestar Runner segment is the demo song of the Casio VL-Tone 29-Key Keyboard.
  • Sweet bears a slight resemblance to Noisemaster from the webcomic Cucumber Quest, which Toby Fox has composed music for.
Sweet overworld unused walk.gif
  • In the game's files, Sweet has a set of unused overworld walking sprites. These sprites cannot be seen in the game as Sweet only uses a set of battle and NPC sprites.
  • All of their attacks are fired on sync with the music beats of their battle song.
  • In their "Junk Work" dialogue, it is implied that Spamton attempted to get them to sneak into Queen's Mansion in order to obtain the EmptyDisk, but they turned him down. The dialogue also implies that Rouxls Kaard used their services to repair the Thrash Machine. Later dialogue implies that Berdly got them to assemble the golden statues of himself and Queen.
  • In Deltarune's files, Cap'n's overworld sprites are all named "hatguy" instead of his name.
  • When Chapter 2 was first released, a bug sometimes caused one of Sweet Cap'n Cakes' attacks to last significantly longer than intended. This was fixed in version 1.06 of the Chapter 2 demo.[5]
  • The milk one band member can use when their HP drops to zero is reused from K. Round's battle.


  1. Those young men have made an interesting shop. They're leaving the bagel business, so I have the rest of their remaining stock. - Seam
  2. 2.0 2.1 In one comment I said they were brothers, but that was not clear. I’m sorry. The nuance may be close to “Best friends”. I can’t give you more details than the officially announced settings. Whether they are best friends, brothers, etc. is unknown. - nelnal on Tumblr, September 26, 2021.
