Hasbro took over the rights to produce Cabbage Patch dolls in 1988 as Coleco went bankrupt, and continued to make the dolls with various gimmicks, including dolls that played kazoos. Some of the more popular doll lines to come out under the Cabbage Patch Kids name included the "Birthday Kids", the "Splash 'n' Tan " Kids, and the "Pretty Crimp and Curl " Dolls. Hasbro gradually began making the dolls for younger children, which led to smaller and smaller dolls. Although Cabbage Patch dolls were still best selling toys, Hasbro never really revitalized the Cabbage Patch market. In 1994, Mattel purchased the rights to the dolls.
