MINNEAPOLIS -- When a 10-year-old girl with a rare genetic disorder invited her classmates to her birthday party, no one RSVP'd yes.
That's when hundreds of strangers chipped in to give her a birthday she would never forget.
According to WCCO, Mackenzie Moretter has Sotos Syndrome, which left her with some brain damage.
"I have a hard time making friends at school,” she told the station.
WCCO reported the girl's mother reached out on Facebook after no one accepted an invitation to her daughter's birthday party.
When people heard the girl's story, hundreds of strangers, neighbors, even big names like Snoopy and Elsa, showed up.
Even former Minnesota Vikings wide receiver Charles Johnson came out to celebrate, WCCO reported.
One guest, Jeannette Vandenberg, is a parent of a child with a similar disorder.
“They go through so much, and I was just excited to come out and see her,” she told the station.
The station said about 400 people turned out for the party, and all of the food was donated from local businesses.
"It means a lot to me for all of you coming to spend time with me,” Mackenzie said.
