Tubee

Tubee (Japanese: チュービー Chūbī) is one of the students of Midnight Horror School, and one of the main antagonists of the series along with Usop and Yumyum. During the daytime, he is an empty paint tube.

Appearance
Tubee's head is shaped like a purple and white tube of paint, with purple paint pouring out of the side of his head and the tube's cap resting on top of his head like a hat. He had green eyes, an X shaped nose, and a stitched-up mouth with purple paint pouring out. The stripes on his shirt are black and green, with a white T decorating the middle.

Personality
Since he is one of the antagonists of the series, Tubee can be oftentimes mean to his peers. He, as well as Usop and Yumyum, could be seen as school bullies, making fun of their classmates and, for the most part, being pretty mean spirited. However, as shown in a few episodes of the show, Tubee also has a soft side that mostly comes out when he isn't around Usop and Yumyum.
