Hutto is affectionately known as the "Hippo Capital of Texas" due to its unique connection to hippos. Legend has it that in 1915, a circus train passing through Hutto had a derailment, leading to the escape of several hippos. Although most were recaptured, one hippo named "Henrietta" managed to elude capture and found her way to the nearby Cottonwood Creek. Today, the hippo remains a beloved symbol of Hutto's quirky history and can be seen throughout the city in various forms, including statues and artwork.
