I found a glitch while doing purity forest. I was Tyrannitar and there was a keckleon in the room, and I saw that Tyrannitars' Sand Veil ability was hurting Kecleon, so I waited there until Keckleon died. I then picked up the stuff he had.
and the dead Keckleon said his "Help! Thief! I've been robbed!" thing. I freaked out and started running every which way trying to find the stairs. But, no Keckleons ever came. I was surprised. After the while it took me to find the stairs, nothing else really happened. This was on Blue rescue team.
