Well, I went to the secret shop in order to get some new spells. I learned Mend Minion and Draw Power. After that, I decided to walk into the secret shop. Upon entering, I saw I earned a badge. I assumed it was secret shopper. However, after looking down, I realized it said "Badge Earned: Ninja Master". I opened my book, and sure enough, right below my PVP Sergeant badge, I saw Ninja Master, and am currently wearing it. No idea how exactly I got this badge, I've only done 20 ninja pig courses.
