Sweetie Blue appeared for sale around the same time that wave 3 had come out. Since ponies with bangs were discontinued during wave 3, it is possible that Sweetie Blue was an earlier variant of Cupcake, who shares a similar symbol. Sweetie Blue also might be a toy of Mrs. Cakes from the Friendship is Magic TV show, as the two have a very similar colour scheme.
