I have a squeek/suggestion! Instead of a grab bag of the baby gothic unicorns, why not do a big batch of limited production to match the Blue Merle and Buckskin adults? If the adults could be $135, babies should be quite affordable if mass produced. I know I would love a buckskin one to go with my blue merle adult.
For a new sculpt like the baby Gothic unicorn Melody almost always does a Grab Bag batch first. Then the sculpt is produced in Limited Production and maybe Production colors for the store.
This has been the pattern for all the recent new sculpts.
