It's the crossover episode that dreams are made of when Lego Masters gatecrashes The Block site this week.
And here, this year's Blockheads speak exclusively to Woman's Day about the moment host Hamish Blake and judge Ryan "The Brickman" McNaught challenged them to one of their most nail biting builds yet!
While they're nailing it in the actual build, father-daughter duo Harry and Tash found building a home out of Lego to be "a real struggle".
"I watched the first season and I loved it, but I didn't realise how hard it actually was to build Lego to such a high standard," says 32-year-old Tash.
"The most challenging part for me was actually finding the parts to really dress up what we build," Harry, 57, echoes.
"I think our talents are strictly renovations... and even that is a stretch," Tash laughs.
"Next time there is a challenge, I want it to be a singing challenge!"
Perth couple Luke and Jasmin admit they went into this challenge completely blind after never watching an episode of Lego Masters.
However, they tease what they make could be the creation to take home the coveted Lego Gnome.
"I know it's Australia's biggest TV show, but we haven't watched much of it," Jasmin admits.
"But we ensured what we made was the best thing we have ever made out of Lego, that's for sure!"
And while chippy Luke, 35, believes his 36-year-old wife did well with what little knowledge they had, he says the couple won't be gunning for an appearance on the show any time soon.
"No, we have no patience for that!" he laughs.
Fun-loving couple Sarah and George were beside themselves when they saw the famous Brickman in person.
"It was so great to meet him," 33-year-old George gushes.
"I'm a bit of a nerd – I just love the show."
And while he may love watching the Lego Masters contestants do their thing on telly, when it came to building his own creation, the electrician found his hands weren't up to the task.
"While I like collecting things, for some reason I have never done Lego – so it was a real challenge," he says.
"Yeah, I think it's best we stick to renovations," Sara, 27, adds.
Living on a remote farm 250km away from Adelaide, Daniel and Jade, both 35, aren't exactly used to seeing famous faces.
So when they were introduced to The Brickman and host Hamish Blake via Zoom, the pair were left in awe.
"It was so great to meet The Brickman – I was a bit starstruck! And speaking to Hamish over the phone – so cool!" says Jade.
Yet while rubbing shoulders with a celebrity had them pinching themselves, the pair couldn't help but miss their children.
"The kids were in our heads the whole time," she adds.
"It was a pity we couldn't have done it with our kids, they would have loved it," adds Daniel.
While other couples joke at the novelty of the experience, Brisbane's Jimmy and Tam are diehard fans of Lego Masters, and reveal they were out to impress The Brickman from the get-go.
"We love the show. We got to binge every episode during the COVID-19 break and it's so awesome," says Tam, 31.
Adds Jimmy, 33, "It was so cool but we were a bit nervous going into it. I thought we were going to be crap and were going to make a fool of ourselves.
"You have so much going through your mind, but it was so great meeting The Brickman, and we loved his advice."
