Schroeder is the love interest of Lucy Van Pelt in "Peanuts", though she isn't his. On an occasion, he's also the love interest of Frieda, but she's not his either. He is the resident musician who idolizes Beethoven so much that he plays his music. He was shown as an infant in a blanket sleeper when introduced, especially to the toy piano he is shown to be using. Although he is a big boy now, Charlie Brown stays a child, like everybody. Schroeder is close friends with Charlie Brown, though he does show moments of anger toward him.
