Forest/NPCs

== Royal Coat Rack ==
The Royal Coat Rack is a Darkner who can be encountered in the Forest. They resemble a gray metal jack with two eyes that protrude from between four of their prongs, while the last two spikes append an elongated body and act as legs. Along with Little Ball, they guard the chest that contains Ragger.
When spoken to by the party, the Royal Coat Rack begs them to take the Ragger, a hand-me-down item which no longer fits them anymore, and use it to defeat King. They explain that they used to be the Royal Coat Rack at Card Castle before King fired the whole staff.
If the party gets past King without harming anyone, the Royal Coat Rack is among the celebrants at Card Castle. Again accompanied by Little Ball, they congratulate the party on their victory, excited to become a coat hanger again. They add that they asked Seam to come to the castle too, but "there was no interest."
In Chapter 2, the Royal Coat Rack appears in front of Ralsei's castle, and says that they will hold Ralsei's hat until he needs it. Later, if the Cyber World's Dark Fountain is sealed without harming anyone, they are weirded out by a bouncing Trashy, who hopes to make new friends.

== Little Ball ==
Little Ball is a Darkner the party can encounter in the Forest. They resemble a small, shiny pink ball with blue lines of discouragement on their face. Along with the Royal Coat Rack, they sit beside the chest that contains the Ragger. If spoken to, they mumble that they are just a little ball and don't want to discuss anything.
If the party gets past King without harming anyone, Little Ball is among the celebrants at Card Castle afterward, and says that even a little ball "can say something like thank you." The Royal Coat Rack again accompanies Little Ball, and their juxtaposition suggests that Little Ball represents the bouncing ball in jacks.
In Chapter 2, the Little Ball appears in front of Ralsei's castle, where they remark that it is a bit scary for them to move to a new place. If Nubert has come to Castle Town, he lends them his wig.
== Blue Blocks ==
The Blue Blocks are Darkners the party can encounter in the Forest. They are light blue, roughly square-shaped with rounded corners, and have pointy yellow feet and darker blue letters surrounding their eyes. B blocks have two eyes and a visible mouth, while O blocks have only a single eye and no visible mouth. They tend to add their letters to words where they don't belong.
Together, a B named Bow-Bow and an unnamed O stand behind the chest containing the Dice Brace. Bracelets are Bow-Bow's favorite, and O suggests, at length, that the party not listen to Bow-Bow since she won't stop talking.
If the party gets past King without harming anyone, two B blocks and two O blocks are among the celebrants at Card Castle, arranged in a line with the two Os in the middle. Each congratulates the party effusively for their victory.
In Chapter 2, Bow-Bow appears in Castle Town commenting on how she's bjust a block. 
== Worm ==
The Worm is a Darkner and minor NPC the party can encounter in the Forest.
The Worm is a worm or caterpillar-like creature and consists of multiple segments of alternating colors in white, green, and pink. They have rosy cheeks adorning their face and two green antennae protruding out of their head. They makes their home by a tree whose leaves are falling.
When spoken to, the worm states that, before the King showing up, they used to eat the leaves that fall from the tree nearby. In actuality, they still do so, and laments: "Such is the way of the worm..."
In Chapter 2, the Worm is seen eating the Dummy's clothes. According to it, the lack of trees forces it to eat clothes to gain nutrients and laments: "Such is the way of the worm..." It is also revealed to not understand taxes upon returning from the Cyber World, as an Addison is charging it to eat the Dummy's clothes.
The Worm may be based on the children's game Cootie, based on their appearance, as well as their sprites being labeled "coody" in the game files.
== Starwalker ==
Starwalker is a hidden NPC the party can encounter in the Forest. In the area with the Starwalker Bird, if the party backtracks after ringing the bell, the original Starwalker can be found on the other side of the path (this can be done from either direction).
If spoken to, he proclaims his displeasure about the birds, declaring that he is the original Starwalker.
If found in this way, the party can encounter him again in the prison of Card Castle, again expressing his distaste (this time for the jail), and once again declaring that he is, indeed, the original Starwalker.
If spoken to, Starwalker reappears in Chapter 2 to join the party alongside Lancer and Rouxls, and stays as a Key Item for the rest of the game, making cameos occasionally.
== Starwalker Bird ==
The party encounters a Starwalker Bird sitting beside a path in the Forest. As they approach it, the Bird rises into the air and pursues the party, firing bullets at them until they reach the other side of the room and either leave or ring the bell. Whichever option they choose, a Starwalker Bird always appears upon entering the room again and continues to attack. If the bell is rung, the original Starwalker can be found on the side of the room where the party entered. If the party enters from the right side of the room, rings the bell, and catches up to the ambulatory part of the bird before it walks out of the room, they receive 40 Dark Dollars "from Starwalker's ambient luster."
One of the rooms in the Forest Maze has two Starwalker Birds, one on each side, that pursue the party. The room has no bell for neutralizing them.
Starwalker Bird resembles a white-winged bird that has a golden head shaped like a four-pointed star, with two small dark diamond shapes as "eyes." The bottom-most point is longer than the others, and has another point behind it to serve as the bottom of its "beak."
The Starwalker Bird's pattern of attack is predictable. The Bird fires three simultaneous and diverging star-shaped bullets aimed at Kris's current position. The party must dodge each attack until they reach the opposite end of the room. The easiest way to dodge its attacks is by running along the path and avoiding any walls.
== Block Tree ==
The Block Tree is a Darkner resembling the general Card Kingdom tree with legs and one single eye. It is hidden within a large round room with a diamond chain rotating around the middle. 
If the party rotates around the center for a while, the room will darken and eventually reveal the Block Tree at the north end of the area. It has a switch that must be pressed to remove the tree blocking the path to next room. 
Pressing the switch will cause the Block Tree to vanish and the passageway to the next room to open.
Alternatively, if the Block Tree's hidden switch is hit before going around the center of the room, Ralsei becomes impressed with Kris and asks them on how they knew the switch's hidden location.

== Scissor Dancer ==
Scissor Dancers (named only internally) are overworld obstacles found in the Forest and Card Castle. They circle an area with a block in the middle, and deal damage whenever Kris touches one. If Kris interacts with a Scissor Dancer like they would with any other NPC, a unique sound effect plays.
== A Man ==
The man is an NPC who offers Kris an egg behind a tree in the Hidden Area. The man's name and appearance are completely unknown. He does not talk to Kris directly; the entire interaction is only explained through the narration. The man later reappears in the traffic jam inside one of the cars, vanishing after being seen, finally appearing in Cyber City in another hidden area in Chapter 2 after getting ran over by the Annoying Dog.
