Jeff is the original purple Wiggle and a founding member of The Wiggles. He was the purple Wiggle for 21 years before being replaced by Lachlan Gillespie in 2013. He has since made cameos in some episodes of Series 7.
Jeff tends to fall asleep a lot, which causes the others to call out "1, 2, 3, WAKE UP JEFF!", and that causes Jeff to jump up and down and do all sorts of silly things.
Jeff plays a variety of key instruments such as the piano, keyboard, accordion, and occasionally other instruments like drums or guitar. Out of the original generation, he sings the least, only having a few lead songs like Would You Giggle, I'm a Cow and I Just Can't Sleep on Christmas Eve!.
