The TzHaar hero, or Tzhaar-Ket-Gor, is a character encountered in the Lava Flow Mine. Players must slow down the Lava monster so the TzHaar hero can catch it. If this happens, everyone inside the mine will have double the chance of receiving gems for the next ten minutes.
The name is based off the April Fools BTS announcing a new minigame called TzHaar Hero, which is in itself a play on words of "Guitar Hero".
It is possible for the TzHaar hero to catch the Lava monster without player aid. Players will still receive the bonus.
Tzhaar-Ket-Gor was graphically updated on 2 November2015, over three and a half years after the rest of the TzHaar.
