This pony was never released, she's a Milky with the so called "amiami" hair style and colors. The original AmiAmi was a green pony with this green hair and style. In general you can buy a Milky and rehair her in these colors.Eh,

The "kurukuru" is the blue hair style according to my understanding. The bangs begin shortly behind the front ahir part on this hair style, while "amiami" begins at the side of the head.
