In 2002, prior to the first episode's airing, Okon drew attention as an inter-Korean joint animation in which he collaborated with North Korea's Samchully General Assembly.

Choi Sang-hyun, who was working at Iconix Entertainment, was given a project of creating a character that represents an animal living in the winter.

The original Pororo was a blue and white, petite penguin sporting an aviator helmet and goggles, which became popular among children.

The creators picked the colours blue, pink and white to ensure familiarity for children, as well as representing said colors for boys and girls.

When making episodes, producers focused to details that could be biased to certain cultural codes or give a historical reference, that is sensitive to viewers in certain parts of the world.
