Surprise! There's a new Wiggles album out on Friday – but it's not what you'd expect.

The beloved children's entertainers have dropped an electronic dance music (EDM) album full of dancefloor-ready remixes of their biggest hits.

Keen Wigglers would know that there was a chance this would be on the horizon, though.

It comes less than a week after DJ Dorothy (indeed, the dinosaur) performed a surprise set at Melbourne's Billboard nightclub, slinging songs from the new album.

The Wiggles Sound System: Rave of Innocence boasts 14 of your favourite Wiggles songs as you've never heard them before, infused with rave flavour and hectic beats underneath some classic Wiggly vocals.

The group worked with DJ Lenny Pearce on the new bangers. Lenny is also the brother of Purple Wiggle John Pearce (aka Big Strong John).

"This project was super fun to work on," the Justice Crew member told ABC News Breakfast.

"I am 33 now, and I vividly remember lying on the floor with headphones on listening to Greg [Page, original Yellow Wiggle] thinking 'wow, this is so soothing'. And then, 30 years down the line, I am mixing his vocals in my studio."

The album features songs that have been doing the rounds for 30 years – think Hot Potato and Fruit Salad – and some newer songs like Baby Shark.

But Pearce's favourite also happens to be the first track on the album.

"I like The Monkey Dance because it is modern pop-sounding. It sounds like an adult tune, but it's Greg's voice … my daughter also loves that, and she is one and a half!"
