I had the MC Hammer doll! If I remember correctly the audio cassette he came with was of “U Can’t Touch This”. I never had the other two dolls, but I remember there being quite a scandal when the Rosie O’Donnell doll came out. Rosie O’Donnell insisted her doll’s figure not be a generic Barbie mold, so they created a ‘fat mold’ just for her. To my knowledge, they didn’t use the mold for any other Barbies.
