Art Pony Pose
From My Little Wiki
The Art Pony Pose, also known as the Core I pose was designed to fit with a range of plastic molded clothing, and to denote this, the (non-Event and non-Art) ponies had a coat hanger symbol as their hoof mark rather than the usual G3 Hoof Heart.
The same basic body shape can be seen in a Unicorn version of the pose, Sweetie Belle Pose, and the Pegasus version, StarSong Pose. Additionally, the same body but with a different head mold could be seen with the Makeup Scootaloo Pose and Makeup Cheerilee Pose.
