We've added another line of toys to the Other Figures Database: The figures from the Russian brand Play Together (Играем вместе). Their line of figures contains the mane 6, but instead of Rarity they included Princess Celestia with red hooves (lucky Applejack didn't get replaced this time). The toys have been out for a while, but we've only recently heard about them. They can easily be mistaken by the Plush Apple figures, but there are some differences (e.g. hair and eyes).
Play Together sells a few variants of these figures, including versions with light or sound. They're packaged in sets of 2, either on cardboard or in nets (Princess Celestia seems to only be released in nets). Below we have some detailed images of the figures and their packaging.
Many thanks to Oleg for all the info and images!
