Cosmic

"Cousin" is a term used to describe a number of beings that have no other known name to describe them with. A more fitting term would be "cosmic", as this species' home is The Cosmos. This term is faulty as it is in fact generally used to describe the relatives of the Prince who happen to be his cousins, but as there is no other term to describe them by, it is often used to describe the species as a whole.

Cousins are extremely variable in overall height, starting at a known size of roughly a few inches tall during their younger years and apparently growing over time to sizes that can dwarf planets, putting them in comparison to Galactus and other massive beings. Their pill shaped heads are apart of their skeletal anatomy. It is most likely that their antennas come off when they reach adulthood. The Cousins come in many variations, but the most common form has a humanoid body with a pill-shaped head. Some Cousins are robotic, but most of them are made via sexual reproduction. Cybernetics are not unheard of amongst the Cousin species. These mechanical cousins are Mag, 8-Bit, Nickel, Drive, and Andro. Other Cousins resemble foods and objects. It is stated that atmospheric pressure and mood can alter their size.

Sexual dimorphism is apparent between the men and women. Both the King and his father have far more detailed and humanlike faces, whereas The Queen's face resembles a child cousin. The Queen is much smaller than The King. Strangely enough, the female cousin Lalala shows no sign of a sex. The male cousins Kunihiro and Lucha are shown to have nipples, but Lalala does not. Her design most likely doesn't have those features due to the game being for everyone. However, sexual reproduction is confirmed. Like humans, they can engage in this activity for both leisure and reproduction, as it is hinted in the game series. At birth, a newborn "cousin" is incredibly small. This is most likely to make childbirth easier, as the pill-shaped head could lead to labor difficulties if the baby was larger. These infants seem to usually be breastfed, which may imply that Cousins are mammalian. Out of all of the mammal traits, they have mammary glands, sweat glands, hair, and give birth to live young. The cousin Daisy is described as a mammal.

Culture and society
Cousins utilize a type of technology known as a Katamari, which is a ball that apparently creates a field of gravity that allows objects to get trapped to it, although a powerful enough hit will dislodge the objects. The Cousins use this to their advantage to replace planets and stars, at the expense of other beings who become trapped upon the Katamari. Because of this procedure they are considered as a whole to be galactic threats, gathering hundreds of individuals at a time when a Katamari is transformed into a makeshift celestial body. However, it is confirmed these individuals are safe.

From what is shown, the Cosmic lifestyle is similar to humankind's. They engage in activities such as playing games, eating, sleeping, and many more. The first game's story is based around The King getting drunk, for example. The majority of their activities seem very normal for human standards.
