A penguin that can only cry out "Gugu Gaga." When happy, it cries "Gugu~ Gaga~." When sad, it cries "Gu... Gugaga." It has various ways of crying. Arrogant and lazy, it flies into a rage whenever something doesn't go its way. It is incredibly weak but looks down on Guest. It is extremely greedy when it comes to food. It gets cocky easily. It's a total weakling. A good-for-nothing who can't do anything. It has filthy eating habits, eating like a dog and letting brown stuff leak from its mouth while eating. It thinks spoons and other utensils are weapons. It loves bullying Fibichupi. It enjoys picking on those it considers beneath it. It absolutely hates baths.
