May 16. To boost attendance in the park, Busch Gardens revealed plans for a $6 million river rapids ride for the Congo section in 1981. In 1982, the Old Swiss House closed indefinitely for structural renovations and white tigers were introduced to the park in the Claw Island exhibit. The Intamin Congo River Rapids ride opened on May 26. For the 1983 season, Busch Gardens added children rides to the Timbuktu and Congo sections. Additionally, the Marrakesh Theater opened in the southern portion of the Marrakesh area with a Moroccan-American dance show. In the latter half of 1983, Dwarf Village was reconstructed to appeal to younger audiences. The Dwarf Village reopened with a miniature log flume, a car ride, and various play areas. In November, Anheuser-Busch issued its intentions to deemphasize and slowly shift away from "The Dark Continent" name in favor of "Busch Gardens" as the name did not catch on with park visitors and was not as recognizable. The return of the prominent Busch Gardens name would bring changes to the slogan and logo. The following year, an Intamin looping starship, Phoenix, opened in the Timbuktu section on June 5, 1984. The eagle enclosure was relocated to a different location under the brewery escalator in January 1985. A new elephant habitat was created in the Nairobi section in 1986. The Moroccan Palace Theater was completed on August 11, and debuted the show, Kaleidoscope, on August 22. Upon its opening, the Moroccan Palace Theater was the park's main venue to host larger style productions. An animal nursery, named the Nairobi Field Station, opened on December 9. The bird show gained a birds of prey segment including falcons, eagles, and owls in February 1987. Busch Gardens leased a pair of pandas from the Chinese government in October 1987, with a temporary exhibit opening in the bird gardens on November 17. To accommodate the pandas, new bird aviaries were built in the gardens. The first panda on loan left in April 1988 while the second left in October 1988. The monorail received electric trains in 1988. The aviary dome was removed in the same year due to the expansion of the brewery. By the end of 1988, park officials were considering several additions such as a new boat ride, another show for the Moroccan Palace theater, new exhibit spaces, and reopening the Old Swiss House. The park had started a refurbishment
