I am trying to find the name of a toy from the 90's. They were little dolls with a pet and they lived in a flower. It looked like a big petal and it opened with a key. One of the names of the dolls was Lacey and her pet were love birds named lovey and dovey.

Sorry if I'm incorrect, but the "Pansies" doll seems to be the closest to your description.

Actually it's the Princess of the Flowers, is what your looking for.
