I was running around on Route 6, I believe, ( It's the route just outside of Driftveil City in Pokemon Black 2) and I saw a patch of shaking grass. Thinking it was an Audino, I went to battle it. But to my surprise, it was a level 26 Unfezant. How is this possible when Tranquils evolve at level 32? Is this just a glitch of some sort?
