Kako is Oobi's best friend. He appears to be of Spanish descent, and often uses Spanish phrases such as "¡Perfecto!" (meaning "perfect"). Kako occasionally displays signs of arrogance, but never lets his self-confidence get in the way of his friendship with Oobi.
Kako has dark skin and green eyes. He wears a red hat.
Kako appears in many episodes of Oobi. He debuted in the "Dance!" short and was last seen in the "Superheroes!" episode.
