This mold is approximately 4.25″ tall, a larger baby pony or adolescent. It is the same shape but larger than Mold 5-09-B1. It originally had a small head with inset eyes; it was remade in recent years with larger head and painted eyes.
Also see Mold QQ, which is a pegasus version.
A fakie of the Gi-Go mold has also been spotted. It has “Made in China” on the bottom of one hoof, but no mold number.
