Maybe his dorsel fin would change color, I don't get some of you, how can you say Atlantica and Halloween Town were bad. They were both put in not only for more story but also to show what Donald's magic is capable of, also Halloween isn't even that scary since it's an E rated game and Nomura was aware that little kids would try to play it and he probably didn't want them to be scared and give up, and it's supposed to be gloomy, it's HALLOWEEN Town, what do you expect from a town with the name Halloween in it little fairies and unicorns?
