Jeff, the Purple Wiggle, is said to represent death, or sleep. He is depicted as constantly drifting off to sleep at odd moments, only to be brought back to the waking world by the exhortations of the other Wiggles. Thus, Jeff is often interpreted in modern texts as being a representation of death and rebirth, or reincarnation - he dies and is reborn into the world, wide eyed and ready to continue playing theaccordion, another symbol of death(as in most civilised cultures, serial accordion playing is punishable by beheading).

Some have attempted to make a link between the Purple Wiggle and the Antichrist, but despite the colouring their appearance and typical behaviour seem to be quite different(for example, the Purple Wiggle has never been known to devour the souls of accountants).
