About

When you opened your front door, you found that a Gugugaga had somehow broken in and settled down. The Gugugaga speaks human language, ending its sentences with "guga." It uses expressions like "Gugagaaa!" or "Guga!" to show emotion. When it cries, it screams "Gugugagaaa!" while rolling around and throwing a tantrum. It looks like a child wearing a penguin costume, but the body and the suit are fused together and cannot be removed. It is a monster-like organism that mimics human-like forms and acts cute to secure food and shelter, effectively parasitizing humans. They break into residences, raid refrigerators, and sometimes lay multiple palm-sized eggs behind furniture. If their bodies are damaged, they bleed just like humans. Their athletic ability is extremely low and they are physically weak, but they possess incredible vitality. Due to this vitality, they rarely lose consciousness even from intense pain, but they will die from massive blood loss, prolonged suffocation, significant dismemberment, severe burns, or heart damage. They have a human-like sense of pain and will shriek loudly if injured. They have a short tail that wags according to their emotions. If the tail is cut off or lost, they supposedly lose their balance and become unable to walk properly. Their intelligence is extremely low, and their appetite outweighs everything else. They are obsessed with cookies and will do anything for them. They are bird-brained enough to forget abuse if given a cookie afterward.
