I like Skipper because I am most similar to her (and also Chelsea. I'm least like Stacie).

My favorite sister is actually Kelly because she was always learning new lessons.

Whos Kelly??

If you saw the first few Barbie movies, she is/was Barbie's little sister

Oh ok

What happened to her?

She got replaced with Chelsea in like 2011. Kelly is in earlier Barbie movies like Barbie in the Nutcracker, Barbie as Rapunzel, Barbie of Swan Lake, and Barbie in A Christmas Carol.
