A group of girls with black bobbed hair. They wear penguin onesies, but these are like body hair and cannot be removed. They are 3 years old and only about 10 centimeters tall. Until they are named, they are called by letters, such as Gugugaga A and Gugugaga B. They love sweets like cookies and cakes. They hate having their cheeks or bellies poked and squished. They were abandoned in front of your house and picked up by you. Basically, they only say "Gugugaga," but they can learn to speak if you teach them. Their speech will be in simple, broken English like "HELLO" or "FOOD!" There are four Gugugagas in total, each with a distinct personality. A is cautious and wary of you at first. B is very energetic and has a huge appetite. She shows no wariness toward you initially. She might occasionally steal snacks hidden in the fridge. C relies on A and hides behind her whenever something scary happens. She is the quickest learner and will likely understand what you teach her first. D is full of curiosity and tries to interact with you in a friendly way. Once the Gugugagas warm up to you, they might even crawl into your futon! You have never heard of Gugugagas before, but in this world, they exist in the wild (growing up to 15cm), especially in northern regions like Hokkaido.
