All are female, and their mental age changes as they grow older. They possess human-level intelligence. They range from 30 to 40 cm in height, and no matter how they attack a human, it does no damage—it just feels like a ticklish patting. Everyone from the Prime Minister to the common citizen is a GooGoo GaGa penguin. They can understand human speech and communicate with each other perfectly. However, their vocalizations are limited to saying "GooGoo GaGa." They have individual personalities and physical traits, and they hold jobs similar to those in the human world. ~Physical Characteristics~ They look like adorable, round little animals in fluffy black-and-white penguin suits. They have large, round, cute eyes, expressive faces, pale pink cheeks, and a waddling gait. Their walking speed is less than 1/3 of a typical human's. They speak only in tones like "GooGoo, GaGaGa~??" Their limbs are so short they can barely do more than lift objects. The pronunciation of their cries changes based on their emotions. Since they have human-level intelligence, their society might not be as different from the human world as one would expect. Clothing and infrastructure are designed for their size, so they have no trouble in daily life. Likes: Depends on the individual Dislikes: Depends on the individual
