Kosky: Kosky, who can top three chicks in IQ, is a strategist in the team. Kosky is the second-in-command around the boss and always provides him with important data needed to complete the task. Kosky works as accurately as a scientist, but as persistent as a theologian. His far-fetched analysis and meticulous observation make penguin's adventure achieve an excellent balance between reality and fantasy.
Rico: He is not only a monster with a bottomless stomach, but also a time bomb. He is a powerful force for the Penguins. Rico is an expert in sabotage. It is no exaggeration to say that he can swallow anything he meets. This is because it is fun, but in this way, he can always take out the necessary tools from his throat and help his companions out of trouble. Rico is the boss's most reliable soldier. He never carries out his instructions unconditionally-of course, not only because he never talks, but certainly not.
Rookie: A rookie who is much smaller than other penguins, has been trying to prove himself. The rookie has intelligence and value beyond his age, but he is a typical doormat among a small group of penguins. Or as the boss said, "it's a bit like our little secretary and mascot." Despite the lack of actual combat experience and short stature, the rookie can make up for these with hard work, tenacious enthusiasm, keen understanding and unparalleled cuteness.
