Maestro マエストロ

The wise old man. Maestro's hair is white and so long that it completely covers his body, and only his facial features, arms, and feet are ever visible; he is also distinguished by two hairs on the top of his head that look like antennae. Maestro often keeps objects in his beard and is sometimes seen fiddling around in it to find the one he wishes to present. He also serves as a mentor to the children of the series. (Wikipedia)
