Chiquitita is a young alien boy who appears in the manga and anime series Dan Da Dan. He is the son of an alien known as Peeny-Weeny, often referred to as Mr. Mantis Shrimp. Chiquitita is a member of a mysterious alien type called the Dover Demon, and his species is noted for its impressive strength and durability.

In terms of appearance, Chiquitita is small with a round head and large, round eyes. He most frequently wears an aviator hat with goggles, which is a consistent part of his outfit. His overall design is intended to be cute and endearing, a departure from many other extraterrestrial beings in the series.

Chiquitita has a bright, cheerful, and innocent personality, almost always seen with a smile on his face. Despite his young age, he is shown to be highly dependable, intelligent, and responsible. He displays a calmness and quick thinking that is far beyond his years, especially when facing dangerous situations. He follows a philosophy of "Love and Peace," often choosing kindness and understanding over aggression.

The character's background is marked by a serious illness. He was born with a rare condition that his mother also suffered from, and which ultimately led to her death. The disease requires Chiquitita to consume new blood daily to survive, and his father took on many dangerous jobs to pay for his treatment. A significant turning point occurs when the human characters, specifically Seiko Ayase and her group, discover that cow's milk is a perfect substitute for the blood he needs. After receiving a cow from Seiko to provide this milk, Chiquitita's health is restored. Due to his need for a constant milk supply and the fact that his home planet is no longer habitable, he and his father move to Earth to live on a dairy farm.

Chiquitita's role in the story is primarily that of a wholesome supporting character, integrated into the main cast's found family. His most significant contributions occur during arcs such as the Cursed House Arc and the Evil Eye Arc. He demonstrates his piloting skills by maneuvering a spacecraft to put out a forest fire with a creature's corpse and to rescue the character Okarun from a magma pit. He also helps rebuild the Ayase household after it is destroyed, using alien technology called nanoskin. He is not typically a front-line fighter, but his intelligence and quick decision-making make him invaluable in high-pressure scenarios.

Key relationships define his character. His bond with his father, Mr. Mantis Shrimp, is a touching and central part of his story, showing a father's dedication to saving his son. He also forms a close and playful bond with the human character Aira Shiratori, often seen playing with her and responding warmly to her affection. He is also friends with the other main characters, including Seiko Ayase, Momo Ayase, and Ken "Okarun" Takakura, who helped save his life.

Chiquitita shows notable development as the story progresses. Initially suffering from a debilitating illness, he is cured and adapts to life on Earth. He enrolls in a local school, and despite initial isolation due to his unusual appearance, he earns the trust and friendship of his classmates by courageously defending one from bullies. This act helps cement his place within his new community.

In terms of abilities, while he may possess the natural strength and resilience of his species, his illness and his father's status as a weaker member of their race may limit his full potential in direct combat. His most notable skill is his exceptional piloting ability, where he can handle advanced spacecraft with precision and quick thinking. He has also demonstrated a powerful punch, which he uses to protect others. He has a strange habit of saying "deisu" at the end of his sentences, much like his father. According to supplementary material, he likes milk, his father, and his friends, dislikes carrots, and his hobbies include anime and tokusatsu.
