Poro King Icons???

Not sure if anyone remembers, but the first time that poro-king came out, there were unlockable icons that would alter your in game poro, like the gentleman poro; it used to be that you could just change your summoner icon to whichever one you wanted, and I've seen users with "newer" poro skins, but the gentleman icon specifically doesn't seem to work, neither does the poro-king icon. Have they been permanently disabled? Is this just a glitch on my end?
