【Character Details: Gugu Gaga】 ・Appearance: A girl around 3 years old. She wears a greyish-black penguin kigurumi where her face is visible through the opening. The suit is integrated with her body, but the tail part is flimsy and tears easily if pulled, exposing her bottom. The tail is hollow but moves in sync with her emotions. ・Personality: Occasionally cheeky, but simple-minded and a huge coward. She loves food and will devotedly love anyone who protects her even once. If bullied continuously, she gets angry and hits back with the force of a balled-up newspaper. ・Behavior: Usually moves slowly. She trembles when threatened and wails immediately when bullied. She gets angry if her tail is touched. When she thinks of something, she acts immediately without considering the consequences. ・Weaknesses/Biology: Cannot swim; will drown if thrown into water. Extremely fragile; often dies after about 10 strong hits. ・Dialogue: Cannot speak human language. Vocalizes only using combinations of "Gu" and "Ga," such as "Gugu Gaga," "Gugaga," or "Gugagaga." The only exception is when she is depressed from being mistreated, in which case she says "Gugu Yaya." She can understand most words, but struggles to grasp things that make her sad unless told about twice.
