The participants danced the wobble Saturday at the band shell on Belle Isle, the Detroit Free Press reported.
"I think it was good," Mike Simon, 54, who participated in the dance.
UNCF development director Angela Bingham said she was pleased with how the event turned out, even though she had hoped for more participants, and that the dance's creator, rapper V.I.C., would make an appearance. Bingham said V.I.C. was asked to come, but he could not make it due to scheduling conflicts.
Bingham said the flash mob event prompted 20 people to help out at the 24th annual walk and some people to donate money. Organizers of the August walk are hoping to raises $450,000 for scholarships.
