Already been said but yeah cliffport isn't actually allied to Gobbotopia, it's just not it's enemy. And it really only recognized it as a nation and opened trade with it due to the Elvin infiltrators harassing the place, Cliffport and Gobbotopia share a disliking of Elves, so if Gobbotopia is being attacked by elves, that both means they are not working with the elves, and they do not like the elves. The enemy of my enemy is my friend and all that.
Ohhh now that would be fun
