Yes it's fondant!
I've made long and thin fondant rope, twist them together and I've made a circle with it. Then I've flattened it... A lot of job! I've done only 6 in a little bit than an hour and my fondant was already made!
I just added cocoa and powdered sugar to the peanut butter buttercream to make a dough.
Rolled and cut some out for the circles, and molded the head and chest (in the shape of a figure 8 ) with the rest.
The eyes and feet are cloves.
