History
On September 11, 1997, Worlds of Fun announced that Mamba would be added to the park.[2] The ride would be a hypercoaster by D.H. Morgan Manufacturing. It would be the tallest ride in the park at 205 feet (62 m). The coaster would be located in the Africa section of the park.[2] Mamba officially opened on April 18, 1998.[3]
Mamba's track was repainted in late 2024, changing its color from red to green.[4][5]
In October 2025, the Missouri Division of Fire Safety conducted a spot inspection of the Mamba following public complaints and media reports regarding seat belt malfunctions. The investigation focused on an October 11 incident where passengers physically restrained another passenger after her seat belt unlatched and a similar report on October 12. Inspectors identified 18 worn buckles that were "not functioning properly", which the park replaced. The ride reopened on October 30 after the park confirmed the repairs, while emphasizing that the primary lap bar restraints had remained fully functional and the seat belts serve as a redundant safety system.[6]
