The Kardashian sisters do business as a team, they socialize as a team and, now, you can watch them change a family's life as a team.

On Sunday's episode of Extreme Makeover: Home Edition, Kim and Kourtney Kardashian and Khloé Kardashian Odom meet up with the family of Carl Joseph-Walker, an 11-year-old boy who committed suicide after being bullied.

And just how do the Kardashians figure into this episode (which, of course, also includes the Walkers ending up with a brand new house in Massachusetts)?

Well, the sisters have been fervent supporters of anti-bullying causes ever since the instances of suicides among young people spiked in the last couple of years.

In honor of the Walker family, they organized a rally featuring a performance by their pal, Demi Lovato—who has also been particularly forthcoming about bullying and the experiences that drove her to seek treatment for mental and emotional issues last year.

And the cause is particularly close to Khloé's heart, as well.

"I was bullied my entire elementary school and high school [experience]," she tells 17-year-old Dominique Walker, Carl's sister, who met up with the sisters at Sears in Los Angeles during her family's EMHE-provided dream vacation to Hollywood.

"I had the hardest time with it and I would never talk about it, I would internalize everything," Khloé continues. "Back then, there wasn't as much social media and I do think that there are so many other ways to attack children [now]."

But words of wisdom weren't all that the Kardashian sisters had for Dominique. Watch the video to see just what the E! stars have planned for her, and tune in Sunday at 8 p.m. on ABC to share the Walkers' entire journey.

"It's a blessing for me to be able to shed light on causes I believe in, to have the opportunity to fight for things I believe in, and have such a great time while doing it," said designer Michael Moloney, whose team prepped the Walker abode for the big reveal.
