This particular Fun World doll is called Milk Shake. These dolls have food/candy themes. An obvious Strawberry Shortcake knockoff, she has a cheap plastic body and thin rubber shoes.

Since I can't find any Fun World doll links, I'll tell you what I know.

There were at least three Fun World dolls:

Milk Shake (pictured above), has red hair and wears a pink & white outfit.

Bubble Gum, has brown hair and wears a red & white outfit.

Chocolate Pudding, has red hair and wears a yellow & white outfit.
