I have no idea. But they obviously stayed on the path they were on to get to Castle Oblivion. How did they get onto that path anyway? I want to know what that letter said. But maybe Pluto was only supposed to lead them so that they could run down the path. They probably lost him along the way but it wouldn't matter if they were already where they needed to be. Castle Oblivion unfortunately just happened to be that place.
I have absolutely no idea. So please no one flame me for my opinions.
