Not many events can combine puzzles, obstacle races, and charitable giving—all while filling the downtown area with people in gorilla suits. Gorilla Challenge accomplishes all of these things in a single afternoon. With annual events held across the country, it is quickly becoming the premier event for raising fun and social responsibility. Several of the event’s clues are designed to bring awareness to topics such as literacy, poverty, environmental concerns, animal welfare, and elder care. Amid these consciousness-raising events, the company’s gorilla-suit-clad staffers make surprise appearances to award participants prizes and collect bribes in the form of fresh bananas or sign-language-speaking kittens.
