Klungo is a green, goblin-like character and one of the main characters in the Banjo-Kazooie series.

Klungo first appears in Banjo-Kazooie and has since appeared in every game of series. Klungo is usually seen wearing a white lab coat. He speaks with incorrect grammar and, like Ssslumber, hisses every time he pronounces the letter "s."
