Fuu, also known as fuulton, fuulto, pooton, dripton, bigton, homoton and Lucas Grabeel is a young guy who is reasonably angry. Fuu has a lot of mood swings. And is therefore often bullied with his moodswings and has been assigned different names to his different moods. There's Mad Fuu, probably the most popular of the names since Fuu is always a little sour. Then there's Sad Fuu. This name plays out most when we see Fuu get angry, and then afterwards sad to be bullied. His face therefore makes a strange shape and with open mouth so he looks like someone who would very much like to die. One of his most artistic names is Happy / Goofy Fuu. As it happens really rarely, and you hardly have time to pick up his mood swing as he is so quickly back to being Mad Fuu afterwards. Only one image of this mood has been captured in the story, and it is therefore really artistic as there is only one copy.

You can put any type of emotion infront of "Fuu", as "Fuu" just is a name to annoy pretty much anyone.
