I should remind you that Equestria has been invaded by Nightmare Moon, Discord, the changelings, giant thorns, Tirek, parasprites, and its entire history was nearly altered by Starlight Glimmer. Not to mention it shares boarders with dragons, yaks, griffons, and the monsters of the Everfree Forest. Also, in the movie, they will have to deal with the Storm King and Tempest Shadow. All I'm saying is that a little caution might be warranted.
