They're celebrating their annual Zoobilee, and admission is just one dollar!
The event was open to everyone and all Bay County families were encouraged to bring their children and friends out to enjoy the zoo.
You can see many animals including Sidney the friendly giraffe, as well as many endangered species. There will also be drawings for prizes, free giveaways, and you can even take your picture with the animals.
More than 15,000 Bay County residents have taken advantage of Zoobilee over the past three years.
Stephanie Willard, Director of Education at Zoo World, said, "We want to make sure that everybody in our local area, is they only get to make it out to the zoo once a year with their family that they get that chance to, so it's only a dollar admission."
Zooworld's Zoobilee ran Sunday from 9 a.m. until 4:30 p.m.
