To add to the Goblin King's rock star aspect, Froud designed him a sceptre topped with a crystal ball as "a visual echo of a microphone". The sceptre also functions as a swagger stick and riding crop, as Froud regarded Jareth as "the proud lord of the manor, lord of his goblin domain, with his hounds at his feet, ready to go hunting for human souls." Hanging from his neck and adorning his leather jacket, Jareth wears the "goblin symbol". Froud's son Toby, who as an infant played "Labyrinth"'s character of the same name, stated that the Goblin King is meant to be a sexual icon and a temptation to Sarah. This fact was accentuated by a prominent codpiece built into the costumes. Jareth's deliberate sexual allure alludes to "the dark fairy in folklore [who] are meant to be tempting," Toby said. The white barn owl that appears in "Labyrinth" "is one of the many manifestations of the Goblin King", according to the film's early production notes. Henson described the owl as "vaguely...the symbol of the Goblin King." Jareth as the owl was performed by a live owl and a puppet owl built by the Creature Shop in alternating shots. The computer-generated owl that flies over the film's opening credits was created by animators Larry Yaeger and Bill Kroyer, and marked the first use of a realistic CGI animal in a film. David Bowie performed as Jareth three of the five songs that he wrote for the film's soundtrack: "Magic Dance", "As the World Falls Down" and "Within You". "Magic Dance", which has been described as "a full-blown Muppet showstopper", is performed along with spontaneous dance by Jareth and his goblins to entertain baby Toby at the castle. The dialogue starting with phrase, "you remind me of the babe" that occurs between Jareth and the goblins at the beginning of the song is a direct reference to an exchange between Cary Grant and Shirley Temple in the 1947 film "The Bachelor and the Bobby-Soxer". "As The World Falls Down", described as a "sparkling, subdued ballad", is sung by Jareth to Sarah during a dream sequence at a masquerade ball, and through which he avows his love for her. Henson wanted the song to be "fairly old-fashioned in its sentiments", according to Bowie. Jareth sings "Within You" at the film's climax before his final confrontation with Sarah, in a room full of staircases based on M. C. Escher's "Relativity".
