It is a bit of a process, but keep checking in the hut after ever game level increase. You may not have to get max, just to level one or two. Sorry, haven't done this in awhile, that is why I keep forgetting bits of the whole process.
Your welcome! Just to update, I just got to maximum level game rank and saw that the Protector became available for 2500 coins in the hut. I think it is level 2 it unlocks, but you can get to max just to be safe. Lol.
