was poor (eliciting many guest complaints), made Night Safaris unfeasible to continue regularly. In 2004, much of the savanna's drainage system had to be replaced. The attraction remained open during the rehab, with green tarps covering the construction sites to keep the animals out. Between 2007 and 2009, the trucks were extended with an extra row of seating, allowing for more capacity. Also, the safari script/story were significantly changed, placing less of an emphasis on the "Little Red" storyline, and more about the animals in the reserve and the need to find a lost elephant at the end. This led to a somewhat confused plot in which guests are searching for a lost "mother elephant" and eventually find her baby which, according to the story, had already been safe the whole time. In July 2010 it was announced that guests will soon be able to go on "guided treks" around the savanna. This will include areas that are not part of the regular ride experience. On February 10, 2012 it was announced that the "Little Red" portion of the ride would be replaced with a zebra exhibit. It opened in the fall of 2012. The attraction housed Hartmann's mountain zebras, but these were removed four months after their arrival due to "acclimation" issues. Some reports claim that the zebras were fighting each other, biting at vehicles or each other, standing in the road, or just causing issues due to excessive mating behavior. They were eventually replaced with addax antelope. In 2016, Night Safaris were reintroduced as a part of the expansion of Disney's Animal Kingdom. The nighttime changes included a "sunset," animal sounds, and the introduction of hyenas and painted dogs to the reserve. The ride path was shortened for the night safaris in order to avoid areas where no animals would be visible. Incidents Initially, there were a number of animal deaths from disease, toxic exposure, maternal killings, and park vehicles. The United States Department of Agriculture investigation found no violations of the Animal Welfare Act for the 29 deaths that happened September 1997 – April 1998. In June 1998, the death of a hippopotamus from probable pneumonia caused a 40-minute closure of the ride. In July 2007, a man broke his ankle after jumping out of a ride vehicle. In February 2008, a small fire broke out at the front of a ride vehicle. A woman was taken
