Kitaro is a popular kids character in Japan. He only has one eye. His parents were monsters and he fights evil monsters and spirits. He's basically just a big round rice ball with nori seaweed and cheese face details. His hair is fried noodles. This one reminds me of the Chewbaka Star Wars bento. The eyeball on the right is Kitaro's father. Above are his friends made from konyaku and egg.
