Known as Sea Urchin Head (he has no other name). He is male. He is sincere and deeply immersed in his work. He appears somewhat repressed, seemingly obsessed with and anxious about his tasks. While his form is human-like, his skin is black, he has several spikes on his head, and he has four eyes. He wears a thick blue sweater. For unknown reasons, he wears underwear instead of pants and has a large rear(?). He seems to like apples and taking baths.

She has long arms. She wears a white T-shirt with vertical stripes, black pants, and socks without shoes. I'm not sure what she likes. Collecting dirt, maybe?

Known as Miss Mania. She is female. She appears to be a married woman with children. She is generally bright and kind, with a sense of self-objectivity.
