According to local legend, it was in 1915 that a circus train stopped in Hutto at the depot to take on passengers, pick up and deliver mail and possibly take on water and fuel for the steam locomotive. The circus train workers also would have taken this opportunity to care for their animals. At some point during this historic layover, the hippo got out of the railcar and made its way to the nearby Cottonwood Creek. This caused much consternation for the circus workers. Local farmers and merchants watched the commotion in amusement and with interest as unsuccessful efforts were made to extricate the hippopotamus from the muddy waters of Cottonwood Creek. It is said that the Depot Agent, who at that time would have been Hal Farley, Jr., telegraphed the communities of Taylor and Round Rock that were eight miles to the east and west of Hutto to the effect of: “STOP TRAINS, HIPPO LOOSE IN HUTTO”. After much effort the hippo was prodded from the mud and water that resembled its natural habitat and was reloaded back onto the train car.
