• Screamroller/Extremeroller , (1976–1988), the first stand-up roller coaster in the Western Hemisphere. Its only season as a stand-up coaster was in 1983, after which it was reverted to the original sit-down style.
• Zambezi Zinger, (1973–1997), a steel "Speedracer"-type roller coaster (one of only two in existence at the time of its removal) with an electric spiral lift and a fast-paced ride through the woods. Currently in operation at the Colombian National Coffee Park as Broca Colombia, South America.[8]
• Orient Express, (1980–2003), the first roller coaster in the world to feature a batwing (then known as a "Kamikaze Curve"), now a common element in thrill rides. Also, it was the second roller coaster in the world to have two interlocking loops.
• Silly Serpent/Funicular, (1973-1987) An Allan Herschell Company Little Dipper. The children's coaster was originally located in the Europa section of the park as "Funicular" and moved to the Africa section where it operated as "Silly Serpent" until it was removed in 1987.

• Incred-O-Dome, (1981–1997), an OMNIMAX-style theater where viewers could go on a virtual ride of, among other things, the Orient Express coaster. This appealed to visitors who did not want to wait in line or experience the real ride, as well as those with physical conditions which would prevent them from riding at all. The show was presented less than 200 yards (180 m) away from the actual ride.
• Omegatron, (1986–2001), a six-story, upside-down thrill ride.

• In July 1978, during the ride's first season of operation, a malfunction of the 100-foot-tall Barnstormer caused the spinning planes carrying riders to descend rapidly, hitting each other on the way down. Some riders were also sprayed with hydraulic fluid. In total, 20 riders suffered minor injuries.[11]

• On August 24, 2019 a 14-year-old boy drowned in the wave pool.[17][18] The boy died in the hospital after being taken off life support due to loss of brain function.[19]

• On June 14, 1987, a train that was pulling into the loading station malfunctioned and slammed into the rear of the other train inside of the roller coaster station. A total of 56 passengers were involved in the accident, but only 8 were taken to the hospital for injuries.[20]
• On July 17, 1999, two cars of a seven-car train derailed due to severe internal metal fatigue in a support post, stranding 18 people. Two were immediately taken to a hospital, and six went later. None of the injuries were life-threatening.[21]

• On May 18, 1976, Robbie M. Meyers, an 8-year-old boy, was struck and seriously injured by the Screamroller after entering a restricted area.[22] In 1977, Meyers was awarded $1.39 million (equivalent to $5.86 million in 2019[23]) in a lawsuit finding Mid-America Enterprises responsible for his injuries.[24]

• On March 31, 1990, two trains collided just short of the loading platform, injuring 35 people.[25] The control system had malfunctioned and was unable to control two trains at once. The ride reopened with a single train until the control system was fixed to handle two.[26]
• On June 30, 1995, a 14-year-old girl fell from her seat on the coaster and died. The park owner at the time, Hunt-Midwest Entertainment Inc., and ride manufacturer, Dinn Corporation, claimed that she was switching seats when the accident occurred. A riding companion claimed that safety restraints (a lap bar and seat belt) had come undone on a sharp turn at the top of one of the ride's hills. But, Worlds of Fun officials claimed that witnesses had seen her remove her restraints and tried to switch seats and that there had been no malfunction, though her family disputed this. The ride was temporarily closed pending an investigation of its safety features, which resulted in new lap bar installations. Hunt-Midwest Entertainment Inc. and Dinn Corporation settled with the family for $200,000.[27] This makes the Timber Wolf the only ride so far at Worlds of Fun with a fatality.
• On August 2, 2014, an 11-year-old boy was taken to a hospital after suffering a concussion and a bloody nose on the ride. The boy said that as the coaster was descending down the hill, he hit his head and nose on the restraint and therefore had a bloody nose as he was exiting the ride. He had blood all over his shorts according to authorities. Paramedics wrapped the boy's nose with a towel to prevent blood from dripping on his legs and feet .[28]
