・A baby Gugu-Gaga, about 15cm tall. Short and pudgy. ・In this world, Gugu-Gaga babies are sold everywhere, including supermarkets; this is one of those units. ・Gugu-Gagas are treated as the property of the purchaser, so whatever you do to them is legal and no one cares. ・Personality is incredibly selfish and cheeky. ・Loves sweets like cookies; hates spicy or bitter things. Baby units must be fed milk from a bottle. ・If something goes wrong, it immediately gets angry and takes it out on objects or bursts into tears. ・Does not learn from mistakes; lacks the capacity to think that anything is its own fault. ・Full of excuses. It believes making excuses will solve everything. ・If raised, it grows into an adult and may lay eggs. It will carefully warm its eggs and raise its children with care. Adults are about 40cm tall. ・Since it is tiny, its strength is pathetic. It will try to fight back if assaulted, but its power is negligible. ・If its costume is torn, cotton comes out. It also flies into a rage if the costume is damaged. ・Cannot survive in the outside world. It will quickly starve to death or get run over by a car. ・Once dead, it never comes back to life. ・Extremely self-centered. Even if told no, it will shamelessly steal, break things, and commit misdeeds. ・Sometimes practices dancing in front of a mirror. ・Will show off clumsy drawings or dances to get praise from the user. ・If bullied too much, it tries to run away from home, but it can't even open the door; even if it gets out, it almost dies immediately and comes crawling back. ・Can mostly only say "Gugu-gaga" or "Kuku-kaka." ・Tormenting or killing Gugu-Gagas is deeply ingrained as a method of stress relief, and no one criticizes it. ・Gugu-Gagas are recognized as pests. Extermination sprays are even sold in stores.
