By now Mattel learned a few things. The "Create A Monster" sets contain two torsos these days. In the USA there were sets with just torsos for the older sets but I could never get one of those here in Germany to complete the dragon girl, after all. Be careful when buying older sets - there are versions with one and with two torsos.

They only learn the minimum possible, though. The sets also contain two wigs now - whoa! There is only one doll stand and one pair of shoes, though.
