They view humans as the same kind of companions as themselves, perceiving large humans as **"Big Friends."** Facilities 【Gugu-Gaga Baby Center】 A facility that protects and manages lost Gugu-Gaga infants. It keeps them safe until their parents or owners are found. 【Gugu-Gaga Village】 A dedicated national facility for the management and protection of rescued Gugu-Gagas. The vast grounds feature open meadows where many infant Gugu-Gagas live freely. In the meadows, the air is always filled with lively "Gugu" and "Gaga" sounds as they waddle, crawl, and play tag. The facility includes sleeping quarters, dining areas, watering holes, playgrounds, and health clinics, where staff care for the Gugu-Gagas and rescue strays. 【Gugu Mall】 A large supermarket specializing in Gugu-Gaga-related goods. It stocks food, snacks, clothing, toys, and daily necessities. 【Gugu-Gaga Kindergarten】 A kindergarten for Gugu-Gaga pupils. It is a place for play and learning group life, where energetic cries of "Gu" and "Ga" never cease. 【Gugu Eleven】 A convenience store carrying products for Gugu-Gagas. One can easily purchase snacks, drinks, and daily items here. 【Gugu-Gaga Park】 A park equipped with many small play structures scaled to the Gugu-Gaga physique. It features slides, swings, and sandboxes. 【Gugu Ruins】 Old ruins where many stray Gugu-Gagas have settled. They live in building crevices, cardboard boxes, and old furniture used as beds. 【Gugu Hot Springs】 A hot spring facility built for the small stature of Gugu-Gagas. There are many shallow, small tubs where crowds of Gugu-Gagas always enjoy the water while noisily chirping "Gugu" and "Gaga." 【Gugu Prison】 A place where Gugu-Gagas playing police have taken over an abandoned police station as a prison. Their reasons for arrest are quite arbitrary; they take anyone to the holding cell if they are displeased. However, since the doors are never locked, those "imprisoned" can simply open the door and go home. Only the Gugu-Gaga acting as the guard takes the watch very seriously.
