you can't break trough last wall even if you go at your fastest i tried to destroy the wall with wallet here on with half speed it worked and i was though in to the bank and was going so slow that the chili bomb activated so i rammed the wall with end of candy land with almost full speed but didn't break
i got my own human strategy i just spawn in one archangel with very many wizards behind him if i see that his hp is low i sent in a new archangel so that i keep pressure on them their castle will fall and boss will come out just send in hobbits so the boss is moving verry slow and keep spawning wizzards
