Some species in the Valley, namely unicorns, pegasi, and hippocampi, have more than one possible adult pose. These poses are respectively called V1, V2, and V3. In general, V1 poses are more common, and V2 poses are uncommon or rare. However, a few colors only have a V1 pose, and some only have a V2 pose. Although it is most commonly customs that only have one pose, some non-custom colors, such as the Classic Gold unicorn, also have only one. If a color has more than one pose, there is no way of telling which one a horse will become until it grows up.
V3 poses are a special case, as they are only available as Gold Customs or Gold Boutique-exclusive colors.
Below is a comparison of the poses.
