The app, called "Plastic Surgery & Plastic Doctor & Plastic Hospital Office for Barbie version," doesn't appear to be linked to Mattel, which creates Barbie.
It shows kids ages 9 and up how to "suck out fat from an unfortunate girl who has so much weight no diet can help her."
That is until Everyday Sexism, which according to its website exists to catalog sexism experienced by women on a daily basis, got involved.
It asked iTunes and Google Play on Twitter to not only take down the app, but apps like it, and the tweets sparked hundreds of retweets and outrage. Thankfully, since then, the apps have been removed.
