Tessa Prothero of Royal Oak, Michigan, was celebrating her ninth birthday recently with her family.
Tessa is battling brain cancer, so a big party with lots of people was a bit to much for her to handle.
But that didn’t stop a flash mob of 300 dancers from showing up in front of her home to put on a surprise dance routine in honor of her big day.
At first, Tessa was shy and didn’t know how to react to all the attention. But, she eventually stepped out onto the porch of the family’s home to see and hear the “Happy Birthday” routine, which featured hundreds of red balloons.
The flash mob was the idea of Gilda’s Club, an organization that offers free support for cancer patients and their families.
The effort certainly did help. Tessa’s dad said he could tell that the event made Tessa feel good and brightened her spirits.
