Fifth Wiggle was a segment on Sprout's Wiggly Waffle where JB would introduce the "fifth wiggle," a Sproutlet's head cropped onto a body with a green skivvy dancing with The Wiggles to one of their songs, submitted on SproutOnline.com. Viewers could submit themselves dancing to one of the band's songs to have a chance to see them on TV. The segment also got its own app.
