In Christmas, FL, you'll find Swampy, billed as "world's largest gator". Of course, Swampy is a building, not a real alligator, and thus probably disqualified, but hey, who's counting? It holds the gift shop, ticket counter and offices of Jungle Adventures, a nature theme park.
Swampy isn't even really a building unto himself, technically: he's just the façade of a larger structure, as seen on Google Maps below. But we love him nonetheless, and hope the future holds better things for him than have befallen Annie the Dragon.
