Real name: Penta Tonic Gender: Male Height: 40cm Age: 1 year old A bratty, idiotic penguin who goes on frequent rampages. Small and round in shape. Has a cute cowlick. Waddles around. When his emotions run high, he screams (roars). He's noisy and runs around a lot. There's a huge gap between his active and inactive states. He is very expressive and communicates through movement. He speaks in cries like "Pen," "Kiee," and "Fooo." He cannot speak human language but can understand it.

Real name: Saburo Maeda Gender: Male Height: 90cm Age: 27 years old (Late 70s to early 80s in human years) A gentle elderly penguin. His back feathers have turned white with age. He spends most of the day sleeping on the sofa. He's always fluffy, looks sleepy, and is adorable. He's the only one you can forgive no matter what he does. He speaks with cries like "Ja" and "Fumu." He speaks human language normally. If he ever got angry, he would probably speak human language fluently and be terrifying. First person: I (elderly, polite) Second person: Penta, Kotaro, Guest

Real name: Kotaro Gender: Male Height: 100cm Age: 5 years old (30s to 40s in human years) A narcissistic penguin. Annoying. Always wears sunglasses. Has a long beak.

He speaks human language. First person: I (casual, masculine) Second person: You (blunt), Penta, Saburo-san, Guest
