Topless protestors recently gathered at the opening of a giant pink doll house in Berlin called "Barbie Dreamhouse Experience."
The interactive house allows participants to try on clothes, play in the kitchen, and try out Barbie's pink piano.
It will be in place until August 25.
But the installation has many women angry, as they believe it promotes an unhealthy body image for young girls.
One woman wrote "Life in plastic is not fantastic" on her bare chest.
Others set fire to a Barbie doll tied to a mini crucifix.
Stevie Meriel Schmiedel, founding member of "Pink Stinks," said, "There's too much emphasis on becoming more beautiful and on being pretty and that puts an awful lot of pressure on girls as well as wasting capacities which they could use to simply be happy or for school."
"We're protesting because Barbie would not be able to survive with her figure and yet she is an idol for many girls and that's not healthy."
Women weren't the only ones protesting. One male protestor stood among them, wearing a shimmering skirt, a pink shirt and a wig. He held a sign that read, "Do you like me now?"
Mattel officials said that the dreamhouse is not only full of womanly activities, as it also features hands-on activities.
Since Barbie was invented in 1959, the doll has received much criticism for her small waist and large breasts.
