In 1988, Geauga Lake celebrated its centennial by introducing the Raging Wolf Bobs, a wooden roller coaster with a hybrid twister/out and back design modeled after the original "Bobs" roller coaster at Chicago's defunct Riverview Park. Two years later, the park re-themed the children's water area as Turtle Beach, which was advertised as the ultimate children's water playground. Geauga Lake expanded its midway with The Mirage and the $2.1 million Texas Twister in the early 1990s.
