The unnamed singing hippie is a music-loving man who attended Woodstick.
In the episode "The Love God," Stan Pines is irritated by his music, pushing the former into a state of panic. Later, the hippie attends Woodstick.
The hippie has a thin build and slouches. He has pinkish skin, curly, light brown hair, a large beard, and leg stubble, as well as visible eyebrows, a rounded nose, and a gap between his teeth. He wears a dark red beanie, black t-shirt, green shorts, brown sandals, and white wristbands. He carries an acoustic guitar.
