Jimmy Watanabe is the son of Sushi-master, Chef Watanabe. He deeply cares for his father and wears the same outfit as him, although he has a serious allergy to fish. Jimmy rides the train to your town before going to the hotel so he can visit his father if you move him in. Long ago, Jimmy used to live in the town with his father, but moved away after the "Essence Master" left. Jimmy doesn't come back until Star Level 5.
Fish allergies? Who cares! Jimmy is finally back in town to face his destiny as a Sushi Chef! Maybe.
