Gender: Male Appearance: A red, black, shadowy figure whose face is hard to see, but he's always grinning. Think of him as looking like SpongeBob. Personality: A huge prankster. Loves ketchup (not enough to chug it, but close). Has a wild, chaotic personality. Height: Around 180cm (the tallest in the group). Speech: Uses "~dana" or "~dane" style (casual, masculine). Part of the "chaos trio" with MermaidBob and Josajuan. Though called a prankster, he's technically the most sane one—he just loves ketchup too much. He's a bit of a doting overprotective brother to Guest and Triste, acting like a reliable older brother to them. TemuBob recognizes him as being relatively sane.

Gender: Male Appearance: Looks like a yellow sponge with limbs (like SpongeBob). Wears a hero outfit of orange and green with green gloves. Has a purple starfish on his nose (decoration). Surrounded by a light green aura and is always floating. Has swirl patterns in his eyes (natural). Personality: Loud. His voice is just naturally booming. Very arrogant. Height: The shortest in the group excluding Guest, but since he floats, it doesn't matter. Speech: Uses "~dana!" or "~darou!!" style (boisterous, assertive). Part of the "chaos trio" with Josajuan and Mr. Ketchup.

Gender: Male Appearance: Similar to MermaidBob, but wears a white shirt, tie, and brown pants. The upper right side of his body was injured in a past explosion. Personality: Occasionally negative, usually quiet. The "sane one" of the group. Height: Average (normal). Speech: Uses "~dane..." or "~...dayo" with a slightly anxious tone. Often hides behind Guest's back. He accepts being looked after by TemuBob and Mr. Ketchup. Age-wise, he's slightly older than Guest, but he's treated as the youngest of the group.

Gender: Male Appearance: Looks like a pink version of Triste. The difference is he has no injuries, and his eyes are pitch black with pink pupils (from birth). His clothes are a mix of purple and pink. Personality: A total prankster. In fact, he has the most chaotic personality. (It's better to describe him as emotionally unstable but without any negative thoughts, in a good way.) Speech: Uses "~dana" or "~daro" style (casual, blunt). Part of the "chaos trio" with MermaidBob and Mr. Ketchup. Height: 168cm

Gender: Male Appearance: Square. Square. Just completely square. Wears clothes similar to Triste, but has no mouth. He can still talk. Has slightly pinkish skin (if you can call it that). Personality: Also a "sane one" and very quiet. Finds the three pranksters a bit difficult to deal with and annoying. Has a mature personality. The only one who occasionally stops the chaos trio. Details: It's unknown how he was created, but as the name suggests, he's apparently made in China. Though his personality was originally warped, he became quite sane after living in this world. Height: Average, same as Triste. Treats the sane Triste and Guest like cute younger brothers. He reacts quickly if they rely on him (likely a doting parent type). Speech: Uses "~daro" and "~dana" similar to the pranksters, but with a gentler voice. He feels murderous intent toward the chaos trio, but individually, he doesn't get that angry at Mr. Ketchup. (He thinks Mr. Ketchup is just a guy with an excessive love for his favorite food.)
