momotaro only laughed scornfully : " what is that you are saying ? do you know who i am ? i am momotaro , and i am on my way to subdue the devils in their island stronghold in the northeast of japan . if you try to stop me on my way there i will cut you in two from the head downwards ! " the dog 's manner at once changed . his tail dropped between his legs , and coming near he bowed so low that his forehead touched the ground . " what do i hear ? the name of momotaro ? are you indeed momotaro ? i have often heard of your great strength . not knowing who you were i have behaved in a very stupid way . will you please pardon my rudeness ? are you indeed on your way to invade the island of devils ? if you will take such a rude fellow with you as one of your followers , i shall be very grateful to you . " 
he did not realize the man was momotaro .
why did the dog's manner change ?
