Barbie Belly Button Leg Mechanism

So this is how the legs are attached on a belly button body. I don't normally post pictures of stuff like this, not that I do this often, but I thought it was interesting. I wanted to get a sewn-on dress off her without ruining the dress so this was the easiest option. You can also see the dress stains in this picture. Anyway the legs are reattached again and I don't see or notice any differences ;)
