This pose has its origins in Simba’s Lady-Pony and baby, which were sets of a Sweetheart Sister-type fakie paired with this new mold. Sometimes They are 3.5″ tall with painted eyes. They have “MADE IN CHINA” and “1” stamped out across all four hooves. They may have Fancy Pants-style painted diapers or regular symbols (or no symbols at all, usually in wedding sets). Gi-Go sometimes uses the Simba star symbol, but I believe all pictured here are modern Gi-Gos, not Simbas. More information on Lady-Ponies on Vetten’s site.
