Great design. Bold character. Deep Voice(I imagine it). Glowing charisma and more than enough potential to be a very attractive part of the game.
As a boss its really underwhelming. Doesn't give as much money as the rest of the bosses. 3 consecutive win shinies are very cool, but most players pass on it because money is the #1 target for doing bosses. Hope to see it get buffed and his rewards increased as well. Its a small implementation that I hope can be done anytime in the future (when there are not too many other tasks being prioritized)
Edit: It would also be very cool if he gives some special extra prize during Halloween Event.
