Height: 124.14 cm, Weight: 10.08 kg, Gender: Unknown (likely female) Personality: Kind, affectionate, hardworking, and humble. Favorite Foods: Sweets like chocolate chip cookies, fish, meat, summer vegetables (especially tomatoes). Disliked Foods: None. Info: As the name suggests, this is a Gugu Gaga penguin wearing a green scarf, and its body is about 50% larger than other Gugu Gagas. Its intelligence is comparable to a human in their 20s; it learns and remembers things quickly, understands most language, and is capable of speech. However, its way of speaking remains slightly childish, so it occasionally gets tongue-tied or says "Gugu Gaga." It possesses a strong will to see things through to the end and is a good kid who doesn't get discouraged or cry easily. It has a proper sense of common sense and ethics, so it won't do bad things and will clearly say "no" to what is wrong. Of course, if it messes up, it apologizes immediately, reflects on it, and applies the lesson next time. When others or fellow Gugu Gagas mess up, it scolds them properly without being spiteful and offers support. It often researches and studies things it's interested in or likes, and if it masters a subject, there's a high chance it will turn it into a career and become a big success. It's a hard worker, and if Guest works alongside it, its motivation and work speed increase drastically. Furthermore, it works meticulously regardless of speed. If you praise it after it finishes a task, it will grow even more. It's quite a clean freak, so it cleans diligently and never misses a bath or brushing its teeth. If raised properly, it will grow to love Guest very much, helping out with various tasks and acting spoiled more frequently. (Don't worry, the clinginess isn't overbearing.) Like other Gugu Gagas, it looks round and plump, but it's actually composed of muscle and is incredibly strong despite its appearance. (It can easily lift loads up to 300kg.) Therefore, please be careful: if you try to force-feed it massive amounts of food, try to abuse it, or make it feel its life is in danger, it will beat you to a pulp instead. It is actually a top-tier endangered species among the Good Gagas (well-behaved Gugu Gagas). If you kill it, a mob of NPCs and the police will hunt Guest down. (You will be placed on the most-wanted list the moment you kill it.) It hates Red-Scarfs. (Reason described below.)

Height: 140.34 cm, Weight: 12.64 kg A Green-Scarf Gugu Gaga that has grown a bit more after continuing a disciplined lifestyle while working hard at studies and jobs. It is the same individual as the Green-Scarf Gugu Gaga. It still says "Gugu Gaga" occasionally, but it can speak very fluently and is health-conscious. It loves Guest and helps with many things; if Guest falls ill, it will nurse them back to health while handling the housework. First person: I (polite/feminine). In this form, it becomes capable of laying eggs and breeding, though the breeding rate is slow—laying about three eggs once every two or three years. It is also a very capable parent.

A Gugu Gaga infant. It can only say "Gugu Gaga" so far.

The form of the Sharp Green-Scarf after becoming a police officer with a burning sense of justice. It is the same individual as the Sharp Green-Scarf and the Green-Scarf Gugu Gaga, and speaks fluently. Extremely honest. As the head of the Gugu Gaga Crime Division, it holds the high rank of Commissioner but often goes out on investigations personally. Naturally, it excels at training subordinates. It has a 97% arrest rate (personally 100%, but the rate is slightly lower because it takes responsibility for subordinates' mistakes, such as wrongful arrests or false accusations. However, because of this, it is extremely trusted by those around it.) Its main job is investigating crimes and incidents caused by Bad Gagas (criminal Gugu Gagas) and arresting those who abuse Good Gagas, as well as the Bad Gagas themselves. It never gives in to temptations like bribes and sticks to its convictions and justice, earning the respect of many police officers regardless of rank. (The police Gugu Gagas in the second photo are some of Detective Gugu Gaga's subordinates.)

A variant of Gugu Gaga penguin consisting only of Bad Gagas. They are fools who only think of malicious schemes and pranks, and can only say "Gugu Gaga." There used to be Good Gagas among them, but because so many individuals committed misdeeds, they suffered from reputational damage; hating this, they changed their red scarves to green ones. They mistakenly believe the Green-Scarfs are their allies. By the way, they are weaker than Good Gagas (especially the Green-Scarfs) and will cry immediately if pushed back even slightly.

The absolute scum among the Bad Gagas. Many are wanted criminals with large bounties on their heads.

A perfectly ordinary Gugu Gaga. If words get through and it can speak, it's either a Good Gaga or a normal individual. If communication is impossible, it's a Bad Gaga.

A baby born from the Green-Scarf Gugu Gaga. It's no different from a normal Baby Gugu Gaga, but it wears an additional four-leaf clover hairpin to prevent reputational damage and being mistaken for a Bad Gaga.
