Raking in more money than AC/DC and Kylie Minogue, the four Australian men, with a target audience of under-5s, have a career any entertainer would envy.
Since its formation in 1991, the Wiggles brand has expanded from CDs, television programmes and DVDs into a wide range of merchandise.
A Wiggles shop is accessible through their website, from which themed sticking plasters, underwear, shower gel, figurines and even batteries can be purchased.
Theme parks also make it on to the list of moneymakers for them, with a multimillion-dollar park on Australia's Gold Coast and a chain of play centres in the United States.
And the group's franchise extends into non-English speaking countries, with a Taiwanese version of the band launched in 2003 and a Spanish one in 2007.
They have become such a well-known and recognisable entertainment group, in their bright coloured skivvies, they have been mentioned or appeared on television shows The West Wing and Scrubs, and the film Knocked Up.
Original members Anthony Field, Murray Cook and Greg Page met while studying childhood education at Sydney's Macquarie University.
The three began writing children's songs as one of their music projects.
The addition of Jeff Fatt, who played in a band with Mr Field in the 1980s, led to the formation of the Wiggles.
Sam Moran, who had a classical musical background, came into the mix when Mr Page retired because of health reasons in 2006.
This change allowed the band to perform differently because of his classical training.
But their astounding fame has not gone to the heads of the lads from Australia.
"We don't even believe our own success," Mr Moran said.
When they reflected on their wiggly empire, they had to pinch themselves.
He described them as being "inside the bubble" of Wiggles' hype, which helped keep them level-headed.
"We keep each other grounded . . . performing for children keeps you grounded," he said.
Children are at the centre of the the Wiggles phenomenon.
The group's ability to connect with their audience through educational and entertaining song and dance drove their appeal with children and parents alike.
The Wiggles were able to meet many different families from all over the world, and Mr Moran felt their work made a difference.
He said he did not mind the constant public attention.
"The kids are a lot of fun."
The most common questions fans asked were: "Where is Dorothy?" or "Where is the big red car?"
Children could not understand why one member would be alone, because the group was always together during their shows and programmes, he said.
The group was looking forward to performing to New Zealand children this year.
"I'm very excited to come," Mr Moran said.
It had been a long time between visits for the Wiggles (they last toured here in 2002) and he hoped to do some sightseeing, depending on their schedule.
Because success such as theirs did not come without its pitfalls, one of the best parts of the job also proved to be one of the worst.
Mr Moran felt travelling was a gift, but with only one month off a year, long weeks on the road took their toll on the group.
"Being away from my wife for six weeks at a time" was the lowest part of his job, Mr Moran said.
When the group members took their holidays in January, they focused on catching up with family and friends, which provided a break from each other.
Luckily for them, the songs did not stick in their heads, and they were "pretty good at switching off".
The Wiggles will perform two shows at the Regent Theatre, in Dunedin, on April 7.
