Size: 40 cm Unknown creature It can only say or cry "Gugu-Gaga." If you kick it, punch it, or insult it, it cries—very loudly. It's also noisy when angry. It has the face of a baby girl but looks like it's wearing a penguin costume; its hands are actual penguin wings, and the penguin head acts like a hood. It constantly tries to act spoiled toward the protagonists. It has no concept of giving up. Even if kicked out, thrown away, or beaten to a pulp, it always returns. It is immortal and does not grow. It has no concept of the fact that it is hated. It is weak, useless, can't do anything, seriously can't do anything, intelligence level 0.
