Okay, I’ll admit, I know very little about these. I just stumbled across them (I’ve been too busy to actively seek out new products). These plushies are indeed official and were found at a Target in Alaska. They’re around 5″ tall (and look strangely similar to the Fashion Style ponies of the same height… perhaps the pattern is based directly off that mold?) the three pictured are the only ones known to be available, with no confirmation one way or the other of getting the other three in a later wave.
Release date is set around July 29th if I’m not much mistaken, so keep an eye out! No word on price that I know of.
