Baby Face (6) (ベイビィ・フェイス その⑥ Beibyi Feisu Sono 6), originally The 'Invention' 'Needs' Mother! (「必要」は「発明」の母！ 'Hitsuyō' wa 'Hatsumei' no Haha!) in the WSJ release, is the five hundred fifth chapter of the JoJo's Bizarre Adventure manga. It is also the sixty-sixth chapter of Vento Aureo.
Gold Experience transforms the motorcycle into vines, tying Baby Face up. This foces it to abandon the motorcycle and Coco Jumbo; the turtle landing near a group of rockss. Baby Face panics but at Melone's command, waits for Giorno to go get the turtle and attack him, posing as his shadow.
Baby Face seemingly sections Gold Experience's arm, but doesn't see it fall, realising too late that Giorno detached it and made it fuse with Baby Face's own arm. A pirahna comes out of Baby Face's chest, heavily injuring. As a result, Baby Face angrily questions Melone's tactical advices.
