Mascots Under Queensborough Holding's ownership, the park had a single mascot, Woody the Bear. In 2001, Ball Investments introduced the Valligators to the park. The Valligators were three green alligator-costumed entertainers who acted as the park's mascots named Harry, Sally and Baby Al. In 2017, Livingstone Leisure replaced the Valligators with two new dinosaur mascots called Jester and Jasmine. From 2022, new owners Brighton Pier Leisure Group introduced Ebor the Dragon and the next season in 2023, Rex the Valleysaurus. Incidents On 21 June 2001, 20-year-old Gemma Savage died following an accident the previous day when two carriages collided on Treetop Twister, a spinning Wild Mouse roller coaster, which had opened in May of that year. Police decided not to prosecute a maintenance worker, who claimed that he had only received an hour of training on the ride and had not seen its manual. Faulty wiring had also caused a malfunction on the ride. In October 2004, Deputy Coroner John Sleightholme at Skipton Magistrates' Court ruled death by misadventure. Lightwater Valley's owners and electrician Eric Butters admitted to breaching health and safety laws at Leeds Crown Court on 14 November 2006. Lightwater Valley Attractions Ltd was charged with failing to ensure the health and safety of riders. Butters was charged with failing to ensure safety through his work. Both pleaded guilty. A French manufacturer, Reverchon Industries SA, was convicted of two charges of failing to ensure the ride's safe design and construction. In May 2019, a young boy fell 30 ft from The Twister and was left in critical condition. The ride was sold to a UK based showman at the end of the 2019 season. The park was fined £350,000 for health and safety breaches. Energy efficiency In 2015, the park reported energy efficiency savings of around £130,000 a year stemming from an investment in renewable technologies. These include new carbon-neutral biomass boilers producing 400 kW per unit, enabling the park to move away from the conventional oil-based heating system. In addition, a new ground-mounted photovoltaic array was installed in the adjacent fields, which has supplied up to 45% of the park's energy demand. Much of the rest of the energy demand for the rides, including The Ultimate, is met by means of diesel generators. Past attractions The Ultimate The Ultimate was designed by Big Country Motioneering (BCM) and the park's original owner, Robert Staveley. Construction began in early
