Germany: Nesthäckchen-Baby-Ponys
BABY WÜRFELCHEN
Blue baby earth pony with pale pink mane and tail, yellow
building blocks symbol
The only Nesthäckchen Baby to be shown correctly on the advertising insert, Baby Würfelchen's name translates I believe as Baby Little Cubes into English. It's worth noting that her hair is meant to be pale pink, as you can see from my mint in package image above - and any with white hair have faded (this is not a variation).
She was sold with an array of accessories, and was never sold in the United Kingdom.
