Friends Forever #4 is over here. Crystal shenanigans.

5 keys in, the last one to be found in the finale. So what do those girls hope to find in Rainbow Falls? It'll be over a week before we know. Or what Spike hopes to get there, either. But hey, it'll be interesting to see what Rainbow Falls is like when it's not hosting tryouts. Maybe there will even be new background ponies.
