The whole game is illogical (just like a good amount of video games in general).
Right at the beginning, the game is already illogical: You, the player, a human, surname and age unknown,
sitting in a train on the way to your new home. A giant blue/white cat start to talk with you, asking about
your name and the name of the town you want to go to (I just realized that Rover never introduce himself
to you...). You trust this cat and telling him the informations he want to know. You arrive the town and as
soon as you out of the train, a bunch of giant animals welcome you and calling you mayor out of nowhere.
You find out that these animals are waited for their new mayor, who was supposed to come with the train.
They had no informations about how their new mayor would look like, what his/her name would be, they
only know that he/she would come with the train. If you think about it, it looks like they would have
chosen everyone who would come out of the train on this day as their new mayor. And even if you are
confused about the whole mayor thing, you just accepted your fate and become the mayor of this town,
full of animals, as the only human. I think I don't have to say more.
Sure, the game is illogical, but it seems nobody cares about it, as we all still playing this game and have
fun with, just like with all the other video games which are also illogical. To be honest, I sometimes ask
myself if this or that makes sense, but then I don't care about it anymore, because it's a game anyway,
it's fictional, not real, it's pure fantasy, so no worries.
