User blog comment:Iamnoone/Roxy's true fairy level, and a message to my friends/@comment-27111026-20130117063429/@comment-5204941-20130117153622

They already believe magic since they adopt Bloom, Bloom is too young, her fairy power still haven't awaken yet, thus make she can't earn Believix without her fairy power

Stella didn't make them believe in magic, Bloom did, so she can't earn Believix too.
