The green wig has not been seen in the packaging.
The only colour is a bright green across the entire wig.
Style of wig
The wig is visible on some other wig packaging and it appears to be medium length and has straight fibres with a curl at the end.
This wig may have been sold as a separate wig and it is mentioned on the official site that Sophie turns another doll's hair green - by accident.
A website has a green wig that is short in length and has straight hair.
Graphics on the backing card
The doll on the front of the wig pack is unknown.
There are no other wigs that only have green fibres on the wig. A similar wig is found with the First Wave of dolls in terms of length and style.
