All the up and comers in Ponyville are just absolutely up in arms about being invited to the supposed utopia at the bottom of the sea. Well, everypony but Sweetie Belle of course. The whole process of having to leave her home on dry land to move to the bottom of the ocean to a city resting on the sea floor is a bit unsettling for her, but she really has no say in the matter.
