"We are here to watch the kids be happy," the donor told KCNC. "It is just pure. It is happiness because this is really my Christmas."
The donor told The Coloradoan he reached out to some local businesses to help with the donation.
"His generous donation will allow all kids in the store to pick out one free toy, stuffed animal or children's book through Christmas Eve, or while supplies last," Goodwill Industries of Denver spokesperson Jessica Hudgins Smith told KDVR in an emailed statement.
"Go do something good. Make a difference," the donor told KCNC. "Doesn't have to be big. .. I kind of think this is what Jesus would do."
