The first step in skinning a furby is to flip them upside down. Locate the bump in the fabric under the tail (this is where the Ziptie is located.) Cut a small slit in the fabric right where the bump is.

The next thing you need to do is wedge a pair of scissors underneath the now exposed ziptie. Use the leverage to either break or loosen the ziptie enough to cut. Once broken, remove the ziptie.
