I think yoga barbie is a great idea. It gets barbie yet another job with her endless supply of things she can do. As for what she comes with, they may not be ideal to everyone but that's where a childs imagination and parents come into play. If you want barbie to have a mat, get a swatch and tell your kid, this is barbies mat. Some kids may do it themselves! Perhaps tell you kid about yoga more and they may find ways to interpret them on their own.
