Protestors say the Panama City Beach attraction wasn't big enough to house the giraffe it had, much less two more giraffes.
The group gathered at the intersection of Highway 77 and East 23rd Street near Panama City Mall to call attention to their cause.
ZooWorld officials are trying to replace Sydney the giraffe who died this summer. They're trying to raise $50,000 to buy two baby giraffes.
They also say their current giraffe enclosure is three times the size required by USDA and Florida Fish and Wildlife Conservation Commission, but protestors say the attraction should be raising money to expand the animal areas.
