Rainbow Roadtrip may have released a while ago in internet time, but the merchandise is starting to hit stores now for the holidays if you are looking to pick up some molded figures. Apparently their tails gain color when dipped in water.
And joining those, the mini baby ponies. I think they have been in stores for a while though. Have a heads up if you were looking for them!
Thanks to Muddymallow03 for the heads up.
